Process
It started with a recruiter screen with simple checks. Then I went through 3 rounds of interviews. The first 2 rounds were live coding with a deep dive into previous projects. The 2nd round went really deep into every previous work I did from an MLE perspective, with questioning on every possible decision choice. The last was an interview with the team manager.
Questions
There were recommendation system questions. The coding problems were, I remember, LeetCode medium level.
