Alexey Grigorev is a Data Scientist at OLX Group. He’s written a list of 160+ theoretical data science questions. The list includes the following topics:Linear regression and logistic regression. The number of questions in this post might seem overwhelming — and it indeed is. Keep in mind that the interview flow is based on what the company needs and what you have worked with, so if you didn’t work with models in time series or computer vision, you shouldn”t get questions about them.
