I only attended the first interview. The HR had mentioned that this would be a resume walkthrough, and I don't have to prepare much, but it turned out to be a technical interview. The interviewer was asking me MLOps and data engineering questions when my profile mentions no experience of those. I never heard back from them after this first interview.

resume - HR screening - coding test for 2 h (3 questions：sorting， dynamic programming，one I cant remember)- tech interview （online, go throught resume, coding） - tech interview（online） - manager interview（online）

I was interviewed by the group leader and department leader, who asked about my previous project experiences, regarding which model or which method I used, and ended the interview process with an easy leetcode.
