1st round: it was a remote live coding session in a shared coding IDE, so my interviewer could see my code in real time. Two LeetCode problems, one easy and one medium. Because it was a plain script, I had only two test cases hardcoded, and there wasn't a submit button. So it was more about describing my code to the interviewer.

4 rounds of interview, easy - medium difficulty probability/stats questions (standard green book questions) and leetcode hard problems. Queries, Mathematical codings, database design problems were included as well. Experience based questions too.
