Amazon Data Science interview questions

The process was okay; the interviewers were respectful. It started with some SQL questions. Then behavioral and technical questions and typical problem-resolution questions. No major complaints, it would be nice if you refresh your statistics before and practice well previous problems you have solved in your job.

How do you handle categorical variable? What is bootstrapping? Difference between grid search cv and random search cv? Assumptions on linear regression? Overfit vs underfit? It’s was not hard simple and easy. Hope it helps someone
