I was asked very basic sql questions and the interviewer didn’t even want me to write the query. Instead, she asked me to explain the logic to her. She also asked a few very basic statistics questions about type1/2 error, outlier removal - pros and cons, hypothesis testing etc. the interviewer was a manager of applied science
Thank you very much for your reply. I had the first interview, the interviewer asked me some basic to complex sql questions. And she said the next one will be writing complex sql queries.
Then I would recommend practicing windows functions which include rows preceding n etc. i ask them at amazon.
