Candidate-reported interview process
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.
Applied online, then got an email about 10 days later. Had a phone screening a few days after that. The person interviewing me was super nice and helpful, and explained the questions well. They asked about different stats and ML techniques.
