You're welcome. be sure to check out audio fiels to help you prep for Golang interviews

1. What's Golang, and why should I even care?

Just another programming language created by some tech giant (Google, duh) to solve their "problems." No big deal.

2. What's the difference between var and := in Go?

Oh, you mean you don't know the basics? Cool, cool. var is for boomers, := is for the cool kids. Choose wisely.

3. How does Go handle concurrency?

It's just goroutines and channels. Easy peasy, right? 🙃

4. What's the deal with Go's garbage collection?

It's like your mom cleaning up after you, but for memory. Magical, isn't it?

5. Explain Go's interface{} type. Wrong answers only.

It's clearly a placeholder for when you're too lazy to think of a proper type. Next question.

6. How do you handle errors in Go?

Just ignore them and hope for the best. Kidding! Unless...?

7. What's the difference between a pointer and a value in Go?

One's pointy, the other's not. Figure it out.

8. How do you implement inheritance in Go?

Plot twist: you don't. Go said "nah" to inheritance drama.

9. What's a slice in Go, and how is it different from an array?

It's like an array, but cooler. And more flexible. Like you wish you were.

10. Explain Go's init() function.

It's the function that runs before you even know what's happening. Sneaky, right?

11. How does Go handle package management?

It's a wild ride of modules and go.mod files. Buckle up, buttercup.

12. What's the purpose of Go's defer keyword?

It's for when you want to procrastinate on closing your resources. Relatable, huh?

13. How do you handle JSON in Go?

Just throw some json.Marshal() and json.Unmarshal() at it and pray.

14. What's the difference between buffered and unbuffered channels?

One's got a buffer, the other doesn't. Shocking, I know.

15. How do you implement a custom error type in Go?

You could just use string errors like a normal person, but no, you had to be extra.

16. What's the purpose of the go keyword?

It's for when you want your code to go fast. Like, really fast. Zoom zoom.

17. How do you handle testing in Go?

Write tests, they said. It'll be fun, they said. 🙄

18. What's a goroutine, and how is it different from a thread?

It's like a thread, but on a diet. Lean, mean, and ready to concur.

19. How do you handle context in Go?

It's just a way to pass around deadline and cancellation signals. No pressure or anything.

20. What's the purpose of Go's iota?

It's for when you're too lazy to type out constants. Work smarter, not harder, right?

21. How do you handle logging in Go?

Console.log everything. Oh wait, wrong language. My bad.

22. What's the difference between make() and new() in Go?

One makes things, the other makes new things. Totally different, can't you tell?

23. How do you handle method sets in Go?

It's just a fancy way of saying "these methods belong to this type." No big deal.

24. What's the purpose of Go's select statement?

It's like a switch statement, but for channels. Because regular switches were too mainstream.

25. How do you handle race conditions in Go?

Just close your eyes and hope they go away. Or, you know, use proper synchronization. Whatever floats your boat.
