First is about 15-30 min HR call, and then will do a 1H Phone Screen with some coding problems and background check. After that will do virtual on-site. The virtual on-site consists of coding, BQ, and ML.

I applied through the referral and I was contacted by the recruiter a couple months later for the initial interview. I interviewed by the manager who was a nice person and asked about my resume and my experiences, then a coding question is asked through the hackerrank link I was sent before. It was medium question about the permutation generation. I was contacted for the next round of the interviews with three people and all of them asked coding questions while didn’t ask any ML questions. The last person was a very rude asian person. Two days after this, I was contacted for another coding interview!!! And another software engineer asked me medium level leetcode question, I had solved this question before and I solved it, but he started asking many details. I am so confused and wondered why 5 coding interviews with 5 different people for Data Science position!!! That was one of the worst experiences I have ever had in my career!!!
