Candidate-reported interview process
A recruiter reached out and set up an initial chat with someone on the team. After that, I was invited for a full-day onsite interview. They let me know their decision within about five days.
So I had like 2 phone screens and then an onsite. The onsite was 5 interviews total. For the most part, interviewers hammered on ML concepts, and I only got like 1 or 2 coding questions throughout the whole thing.
So I had a technical interview where they asked me some basic algorithmic coding stuff and machine learning questions. After that, I had another interview with the hiring manager. We chatted about the job and they also asked me some technical questions about machine learning and my research.
