Here are the most commonly searched roles for interview reports -
First round is a recruiter screen. Friendly conversation asking about your work experience. Second round is a technical assessment asking 5 SQL questions and 5 Python/DSA style questions. This was particularly hard because you have to answer all 10 in under an hour. Did not answer all of them and as a result did not move on to any subsequent rounds.
While the time constraints were difficult, I don't think they are impossible. A lot of the questions asked are already here on Glassdoor. Had I practiced for a couple more weeks, I think I could have had a better chance to pass. Unfortunately, I only had 1 week between the recruiter screen and the technical round.
Recommendation: Look at all the SQL / Python questions on Glassdoor and practice answering them in under 5 minutes each. Focus on explaining your thought process.

Interview
Good interview - passed the screening. 3 SQL and 3 Leetcode questions. with 25 minutes for sql and python. The questions themselves were pretty easy but the hard part is pace. You barely have time to mess up and debug and you have to move fast while communicating clearly.
