Introduction As an individual who has delved into the world of programming and coding challenges, I have had the opportunity to explore several platforms, each with its own set of advantages and disadvantages. Among the platforms I have utilized are LeetCode, CodeWars, CodeSignal, and HackerRank. Allow me to share my experiences and insights regarding these platforms, highlighting their pros and cons. Leetcode LeetCode has been my go-to platform, primarily because I have successfully solved the largest number of problems here. One of the significant advantages of LeetCode is its vast collection of coding challenges. This extensive repertoire ensures that there is always a problem to suit your skill level or area of interest. Additionally, LeetCode provides more comprehensive and better test cases compared to other platforms. The vibrant and large community associated with LeetCode is another positive aspect, as it allows for interaction, discussions, and sharing of solutions with fellow coders. Furthermore, LeetCode offers a solution working at the backdrop, which provides the correct answer for any randomly generated test case. This feature greatly assists in identifying flaws in your solution. However, it is worth mentioning that some of the problems on LeetCode are occasionally poorly explained. Another drawback is that the output generation feature is not available for interviews conducted via LeetCode, which can be inconvenient. Codewars CodeWars is another platform I have found useful, having solved a considerable number of problems here. One notable aspect of CodeWars is its impressive user interface, which enhances the overall user experience. The platform also offers a good collection of coding challenges that cater to various skill levels. However, a downside of CodeWars is that it lacks the ability to generate correct output for random test cases. In other words, there is no readily available correct solution working at the backdrop, which can make it more challenging to validate your code. CodeSignal Although I did not solve many problems on CodeSignal, I did participate in random coding tests. What struck me as highly advantageous about CodeSignal is its ability to generate correct output for any random test case, even during coding tests. This feature proved to be extremely useful, as it allowed me to validate my code promptly. Unfortunately, due to limited usage, I cannot provide a detailed analysis of its drawbacks and must give it the benefit of the doubt. HackerrRank HackerRank is another platform where I tackled a few problems. It stands out for its abundant collection of beginner-friendly problems, making it an excellent choice for individuals who are new to programming and looking to build their skills. However, unlike the aforementioned coding platforms, HackerRank requires you to write the entire code yourself. Personally, I find this to be somewhat arduous and time-consuming. I encountered an instance where I struggled with a particular problem on HackerRank, attempting to solve it using Python. However, the output had to be formatted as a string with spaces between numbers, which proved to be a tricky task in Python. While HackerRank processed C/C++ solutions for this problem, it lacked the mechanism to process Python solutions. It was an exasperating experience that left me feeling frustrated. Can there be a perfect or a near-perfect coding site? In my opinion, the optimal solution lies in combining LeetCode and CodeSignal. LeetCode, with its extensive collection and robust test cases, serves as an excellent platform. However, it would greatly benefit from adding the output generation mechanism for the interviewing feature as well. This enhancement would eliminate the need to write a separate brute-force solution for stress testing during interviews. Stress testing is not always feasible, particularly for problems for which brute-force solutions are much harder to think of than trivial approaches. Additionally, the time constraints of interviews may make it impractical to carry out stress testing. If LeetCode incorporates this feature, it would become a nearly perfect online judge for programmers. Conclusion Confused about which one should you choose? Well, I encourage individuals interested in coding challenges and improving their programming skills to explore platforms like LeetCode, CodeWars, CodeSignal, and HackerRank. Each platform offers unique merits, such as extensive problem collections, comprehensive test cases, user-friendly interfaces, or beginner-friendly content. By engaging with these platforms, programmers can gain exposure to diverse challenges, enhance problem-solving abilities, and benefit from the supportive coding communities provided by each platform.

There are many repositories on where people upload their solutions to the problems they have solved on . When I started solving problems on , I also started doing the same since it provides as a place to go through the things I had practiced. But as I started solving more problems, it became difficult to manually copy paste them so I wrote a script that can do the same. github hackerrank hackerrank python Currently the script is configured to scrap though the Java and python tracks, and can be configured to add additional tracks by adding them in tracks array. For the source code here is the repository link, first link is of the scrapper and second of my hackerrank solutions for reference. https://github.com/hearsid/hackerrank-scrapper https://github.com/hearsid/hackerrank-scr https://github.com/hearsid/hackerrank-scrapper _Hackerrank submitted solutions scraper and my submitted solutions. - hearsid/hackerrank_github.com hearsid/hackerrank Here are the steps to use it for your account Clone the above repository, or you can copy the required python files. Login to your hackerrank account and copy the CSRF token and cookie from the headers of any of XHR request. (You can check the same in the network tab of chrome devtools) Create a credentials.py file in the same folder and add your CSRF token and cookie in the same. Sample given after 6th point. Go to scraper.py file and add the tracks you want to scrap in the TRACKS array. Go to util.py file and for the tracks update the extension with which you would like to save the file.

Why Developers Hate Coding Skills Tests (And What Hiring Managers Can Do To Change That)

A Forbes 30 under 30 alum and the first Indian founder to go through Y Combinator, HackerRank founder Vivek Ravisankar is out to kill the resume and help developers land jobs based on skill. Davis Baer : What’s your background, and what are you working on? What is HackerRank? : HackerRank’s mission is to match every developer to the right job — with the underlying driver being skill. Software developers can come to HackerRank to practice and prove their skill by solving coding challenges and companies can hire technical talent based on skill. Vivek Ravisankar Today, we are proud to have a global developer community of over 4 million developers — which is roughly more than 15 percent of the world’s developer population — and more than 1,100 businesses like Dropbox, VMware, Stripe, Adobe, Coinbase and Capital One that are using HackerRank to find talented developers. HackerRank has been an incredible journey. It all started as a vision for improving the way developers find jobs. For a bit of background, I was born and raised in Bangalore and Chennai, India. I’ve been interested in computer programming most of my life, and in college I decided to pursue a CS degree. India has one of the highest populations of developers, making the market incredibly competitive. As a result, the best tech companies tend to look for student resumes or profiles with a high GPA from elite universities. The problem is that grades and alma mater aren’t an accurate reflection of true ability. That was certainly the case for me. During college, my friend and eventual co-founder Hari Karunanidhi and I spent hours programming and competing in (and winning!) online coding challenges for fun. We had solid fundamentals and were really strong coders, but didn’t necessarily have the pedigree that recruiters were looking for, especially in such a competitive candidate pool. After graduation, I was fortunate enough to land a job as an engineer at Amazon. I felt incredibly lucky that Amazon recognized my potential and gave me a chance. While I didn’t go to a top-tier college, several Amazon recruiters came to my campus for a coding competition that I was participating in. Ultimately, I benefited from the fact that I was able to demonstrate my skill first-hand. I really wanted to help create opportunities for more developers at scale. During my time at Amazon, I spent a lot of time — hours every week — interviewing technical candidates only to find out later that some of them didn’t even pass the baseline skill requirements. What’s more, for every one position we’d fill, we’d interview roughly 50 candidates. These interviews took up a ton of my time that would have been better spent building products. In fact, Amazon’s CTO Werner Vogels has said that engineers tend to spend 30% of their time just recruiting. At this point, I started thinking back to my own job search experience and the experiences of so many others — including Hari. I realized that people who are more than qualified for a job are often overlooked because they didn’t go to a top school, don’t have a fancy degree, a high GPA or the network needed to get their foot in the door. It became clear that the model for hiring was broken. So Hari and I set out to fix it. Our original idea was around job prep and mock interviews — we called it InterviewStreet — but it didn’t work since students didn’t want to pay for mock interview assistance. Our second idea was a tool to help match Indian students to master’s programs in the U.S. That one didn’t work out either. We realized that in order to create a viable business, we needed to rethink our revenue stream while still aiming to match every developer to the right job. Eventually we landed on the idea of HackerRank in 2011 and were accepted to Y Combinator that year. In fact, we were the first Indian founders to go through YC! It was our third attempt — we applied with the other two ideas, but they weren’t accepted. In the final round of the application process, we were invited for a 10-minute interview in Silicon Valley. I got an expedited business visa, but Hari’s was denied. Three days later, I jumped on a plane to the U.S. for the first time in my life. I landed on Thursday and my interview was on Friday. That trip paid off — we were chosen for the YC Summer 2011 batch. But since Hari didn’t get an H1-B visa, we co-founded the company from Silicon Valley and Bangalore. Seven years later, we still run the company from dual headquarters. What motivated you to start HackerRank? I realized that dependance on the resume as the best predictor of ability is a mistake — frankly, it isn’t a good way to evaluate programmers’ skill objectively. I think at one point, when Hari and I did the math, we realized we were both doing about a hundred phone screens to get one offer at Amazon and IBM. That is unsustainable. Think about how not only inefficient that process is, but also all of the productivity lost by taking engineers’ time away from building new products and services. We thought, there had to be a better way — both for developers and companies. So that’s how we got started. What went into building the initial product? From early on, Hari and I have strived to be very clear about our vision and goals. HackerRank’s north star has always been to level the playing field for job opportunities. We’re both developers, and we made this company to solve a specific pain point that impacts software developers and the companies looking to hire them. As we’ve built and scaled the product, we’ve always asked ourselves “How do we guarantee an outstanding developer experience?” The developer candidate comes first — and this focus on developer experience is a competitive advantage for companies. In terms of the actual code base, HackerRank was initially built using CodeIgniter, a popular PHP framework. Unfortunately, as we tried to build out the platform using that framework, we realized it was not conducive to building and prototyping quickly. So, we decided to move to Ruby on Rails, since the community was pretty active and there was a wide variety of plugins (gems), which made back end development easy and quick. On the front end, we used Backbone.JS since it was a simple framework with a minimal learning curve, and it allowed us to build the first version of HackerRank within a week. Unfortunately, as the application grew, it became increasingly difficult to manage the codebase, which required us to move to React. How have you attracted users and grown your company? Attracting our first users took some time and a bit of scrappiness. We attempted several strategies, including asking my ex-manager at Amazon to beta test the product, but not surprisingly, Amazon wasn’t keen to try out a product that was just built by a couple of guys in a garage. So we had to go back to the drawing board. We decided to create a fake resume that boasted the best of the best credentials and we put it up on various job posts. We ended up receiving a slew of inbound phone calls from recruiters interested in speaking with this “candidate.” And whenever we would receive a phone call, we would say, “Hey you know what, I’m not that person. But, if you use our product we can help you find people like this.” This strategy ended up being really successful in generating demand. We actually secured Zynga as an early customer with this approach. As we’ve grown, we’ve prioritized making sure the platform is easy to use and can deliver immediate value to our customers. Selling to enterprises has also required us to make sure we’re able to cater to their needs, which are very different from startups. If you’re going to sign up a customer like Goldman Sachs, Bloomberg or VMware, you must give them the ability to deploy to large parts of their organization, whether that’s an integration with their existing tracking systems like Workday, Taleo, Single Sign-On or Pins Management. What’s your business model, and how have you grown your revenue? We are a SaaS based application that companies pay to assess developers’ skill. It’s free for developers and always will be. Our revenue growth has been a combination of organic word-of-mouth and having an inbound and outbound sales force. What are your goals for the future? My goal is to build a world where candidates land jobs based on merit. I want to ensure that developers around the world have a way to showcase their skill, that companies are recruiting and assessing candidates based on their ability, and that we at HackerRank are bridging the two to ensure every developer is matched with the perfect job. What are the biggest challenges you’ve faced and obstacles you’ve overcome? If you had to start over, what would you do differently? In Silicon Valley, there is a tremendous amount of emphasis placed on companies to be high growth, which has merit. But companies also need to balance that high growth with good fundamentals. Back in 2014–2015, we were hiring really quickly. I was consumed by the idea of “hyper growth.” I learned the hard way, though, that you must establish a solid foundation that can support that rate of growth while still maintaining a healthy and sustainable business. At one point, I realized that we were growing too quickly for our own good. First, we needed to make sure we were clear on the product we were selling, whether we had a solid product road map to support it, whether we had the right team to build and scale the platform, etc. We took our foot off the gas pedal, which slowed our growth, but allowed us to really focus on building a solid foundation. Now, the company is in a much stronger and healthier state, which allows us to accelerate growth in a smart way. Have you found anything particularly helpful along your journey? Any advice, books, habits, decisions you made that have helped you succeed? I find it inspiring to read about how other successful and creative business leaders have built their businesses and overcome challenges along the way. I recently read “The Hard Thing About Hard Things” by Ben Horowitz, which is a book that every CEO or business leader should read. Oftentimes, the external view of companies is that they are always doing great. However, the reality can be very different. I found it therapeutic to read this book, and it’s an important read for every entrepreneur because it teaches you how to focus on the road instead of the wall when there are so many things changing internally and externally that impact your company. In addition to Ben Horowitz’ book, Y Combinator founder Paul Graham has been a great mentor. He has taught me invaluable lessons, including the importance of understanding that the highs aren’t as high and the lows aren’t always as low as they look. Maintaining that perspective is important at scale. A third concept I’ve found helpful is this idea of being an infinite learner. It’s a concept popularized by Reid Hoffman. Every day, you have a bigger job than the previous day. It’s crucial to think about the skill sets you need and those that are missing to ensure you are continually growing in your career. By taking stock of your skills and those lacking, it is also easier to determine the best course of action to develop and master these skills. What’s your advice for entrepreneurs just starting out? It’s important to build a company that reflects an idea you are passionate about and driven to bring to life against all odds. If you’re building a company for the sake of building it or just to make money, you’re not in it for the right reasons. Building a company isn’t easy. You’ll inevitably come up against challenges you couldn’t have anticipated, have to make trial-and-error choices on decisions that you don’t know the right answer to and face disappointment and stress. If you are not excited about your idea, it will be difficult to weather these hurdles. On the flipside, if it’s a problem that you’re on a personal mission to solve, it’s hard to give up because you’ve fallen in love with the idea. Where can we go to learn more about HackerRank?

Alphabet Amazon Apple Meta Microsoft smash success for chipmaker, Nvidia And while adoption isn’t even across the board yet, corporate America is sitting up and taking notice. At JPMorgan Chase, for example, the company said it had 600 machine-learning engineers, with AI working on more than 300 different internal applications. A recent found that 71% of C-suite leaders said that advancing their use of AI is either a high or medium priority for their organization, with 62% of executives noting that they are worried they’re not moving fast enough with AI. study from UKG That has led to some companies doing “AI washing”, aka exaggerating the amount of AI technology they use in their products or services. While some companies might not be entirely truthful about their motivations and use of artificial intelligence or machine learning technologies, what is increasingly true is that in an AI future, tech workers will need to upskill. The World Economic Forum (WEF) says that “the 2020s are becoming the decade of development for employees and employers in terms of skills and career progression”. Its most recent identified that 44% of workers’ skills will be disrupted in the next five years, and six in 10 staff members will require training before 2027.

I know it can be hard to learn a new programming language. In this article, I want to share my plan with you. It’s a way to learn in eight weeks using videos, articles, and practice exercises. Exercises are very important because I think the best way to learn is by doing them. Python I’ve created this learning plan for people who don’t have much free time. You only need about 30–50 minutes a day and consistency. In my plan, I use the 80/20 principle, which will help you learn the most important things first and improve the rest through practice. For those who read this article to the end, I have prepared a learning tracking sheet to help you track your progress. https://youtu.be/gsnOgtnWqH4?si=mJ-Pfm7Ele-7tsK5&embedable=true Subscribe on my YouTube channel Why You Should Learn Python Python is a very popular programming language. People use it for web development, data science, artificial intelligence, scientific computing, cybersecurity, and more. Python’s syntax is simple and easy to understand, which makes it a great choice for beginners. Its simplicity helps newcomers learn the language quickly. Another important thing is career opportunities. Learning Python can lead to many job options in software development, data analysis, AI, machine learning, and more. What is the 80/20 Principle The 80/20 principle, also called the Pareto Principle, is a rule that says 80% of the results come from 20% of the efforts. If you learn the 20% of Python concepts that are most important and used the most, you can get 80% of what you need to be good at it. This means learning the basic rules, control structures, types of data, and main libraries. Instead of trying to learn everything about Python, focus on the most important parts that help you the most.

Learn Python in 8 Weeks: The 80/20 Learning Plan with Videos, Articles, and Practice Exercises

With the explosive growth of ChatGPT, discussions around how to integrate AI have made their way into corporate boardrooms and product roadmaps at a rapid pace. In fact, AI already plays a vital role in our daily lives. Billions of people spend hours every day glued to apps such as Instagram, TikTok, Facebook, and Twitter, all of which use AI ranking algorithms to personalize your feed. These algorithms analyze thousands of data points per second to predict what a user would like to see most. And the key to getting personalization right is user data. Except, when dealing with user data, it is critical to uphold user privacy laws and protect users from breaches. The mainstream public is still shaken by how used people’s personal data to maneuver politics. Cambridge Analytica According to a report by the Identity Theft Resource Center (ITRC), the US experienced a record number of 1,862 data breaches in 2021. Prominent companies such as Microsoft, LinkedIn, Facebook, Plex, and Cash App experienced significant in just the last two years. data breaches Fortunately, product experts like Sunil Tej Gorantla, who are passionate about building products, are focusing on keeping user data sacrosanct. Having graduated from VIT University, one of the top engineering institutions in India, with a bachelor’s degree in Information Technology, Sunil has a technical background. With more than a decade of experience in product management, Sunil has helped various startups build large-scale web and mobile applications that generate millions in revenue. He is a founder, product expert, growth hacker, and writer who believes in solving what people need, making data-driven decisions, and building products with a strong mission at their core to serve others. During his extensive career, Sunil was fortunate to be mentored by some of the industry's eminent personalities, such as Harishankaran Karunanidhi, Hunter Walk, and Justin Kan. Sunil spent the early years of his career working with leading high-growth early-stage startups. He joined HackerRank as the first Product Evangelist immediately after the company became . To acquire HackerRank's first few thousand users, he spearheaded the campus ambassador program. India’s first YCombinator startup He recruited hundreds of student ambassadors who formed Hacker Clubs at their universities to encourage students to solve programming challenges and participate in weekly programming contests online. He also collaborated with companies such as Airbnb, Adobe, Quora, and NetApp, which hired top programming talent from these contests by being sponsors. However, at the time, retaining users after the contests was a challenge for HackerRank. To improve retention, Sunil implemented gamification and designed HackerRank’s first incentive mechanism to keep users hooked to the product. Working with the team, he launched "Hackos"—a term he coined—which are points users earned by solving programming challenges. Users loved this feature so much that the product's retention rate experienced a significant increase. Sunil's experience scaling HackerRank from scratch to the first 200k users has made his skillset attractive to startups worldwide. His ability to articulate unmet user needs and build product features to drive growth led him to places he least expected. As a Growth Hacker, he helped scale Mobilizr, a consumer tech startup in Nigeria. He also worked as Head of Data for a property tech startup in London. Afterward, he joined Global Savings Group (GSG) in Munich, Germany, as the first Product Owner for CupoNation's mobile web application. In just a few months, he launched CupoNation's first mobile web application in 17+ countries, which tripled the revenue generated from mobile users. Today, GSG is one of the most successful ventures from Rocket Internet, which also spun off Delivery Hero, Zalando, HelloFresh, and Jumia. After leaving GSG, Sunil joined Juniqe, a startup that was ranked as one of the top 3 fastest growing companies in Germany at the time. As an experienced Product Manager, he managed two cross-functional teams to rebuild the entire technical stack, scaling the mobile and web applications to handle millions of users. In addition to leading the Conversion Rate Optimization (CRO) team, he was also the stakeholder manager for Marketing, Search Engine Optimization (SEO), and Customer Relationship Management (CRM). During his time at Juniqe, he played a pivotal role in scaling the product from less than a million to €20 million in annual recurring revenue, turning the startup into one of the largest art e-commerce sites in Europe. While exploring strategies to improve conversion rates at Juniqe, Sunil encountered Dynamic Yield (DY), a personalization solution for e-commerce products. His foray into personalization began as he worked on integrating DY with Juniqe to bring features like “Users who bought this also liked” and “Products you might like.” As one of the first handful of customers to try out DY, he worked closely with DY's team to fix their product issues and share feedback to improve their machine learning (ML) algorithms. This gave Sunil a behind-the-scenes look into how ML was deployed at scale and equipped him to suggest strategies that helped DY become successful. Gartner has named DY a leader in the Magic Quadrant for Personalization Engines for the past five consecutive years. Later, DY was first acquired by McDonald's and then by Mastercard to enhance customer experience using personalization. Armed with the experience transforming user experiences using personalization, Sunil currently leverages his expertise in product development and growth hacking to build Gulpie—a personalized food discovery application. The app helps people discover restaurants based on their unique tastes, while also helping restaurants fight against the manipulation of their reviews and empowering reviewers to monetize their expertise. To create Gulpie, Sunil interviewed hundreds of food lovers, food reviewers, and restaurant owners. Through these interviews, he discovered that a lack of trust in restaurant reviews and user data protection leads to inefficiencies in the current restaurant discovery process, leaving many people perplexed and frustrated. To address inefficiencies in the market, Sunil built a state-of-the-art personalized recommendation engine using an ensemble of cutting-edge machine-learning algorithms. This engine provides users with personalized restaurant recommendations based on their individual tastes, helping them make informed decisions without going through a cumbersome search process. While working on the recommendation engine, Sunil gained key insights into how to deduce unique user tastes. He found that gaining users' trust to share their data requires a promise of user data protection and strict privacy measures. Leaders in the industry like Sriram Krishnan—an investor at a16z who previously built product teams at Twitter, Meta, and Snap—share this sentiment. https://twitter.com/sriramk/status/1631779635376828416?s=46&t=m-tchH2RTFFMPB2qJSBrFQ What Sunil Had to Say Sharing his experience working on personalization at Gulpie, Sunil explains: “Before the invention of blockchains, users were unable to truly own their data as centralized entities held control over it. However, with Gulpie, our aim is to empower users to take control of their data and provide them with better visibility into its usage. We understand that users expect product builders to be cognizant of the skepticism people experience when sharing their data with apps. That’s why we focus on enabling personalization while ensuring that users’ data is absolutely not at risk. We anonymize user data before training our machine-learning models. Additionally, with GDPR and other privacy protection regulations in place, it's important for companies to actively monitor and prevent the misuse of user data to avoid situations like the Cambridge Analytica-Facebook scandal.” In an age where large organizations scavenge user data and abuse privacy without consent, product experts like Sunil lead the way in protecting user privacy. As product managers, builders, and founders strive for personalization without sacrificing privacy, they can rely on experts like Sunil who push the boundaries of what’s possible. With his expertise and vision, we can look forward to a future where user privacy is truly protected, and products can provide tailored experiences that put users first.
