They first gave a phone screen asking about my background and general questions about my resume. Next they set up a 1 hour technical phone interview where I answered questions about machine learning, followed by a case study. The questions focused on what I would do in certain situations, like if there were missing data or if there were outliers. In the case study, I was asked to list features that would be useful for analysis, specify the target variable and indicate which types of algorithms I would use and why I would use them. A few days later I was schedule for a round of on site interviews. I was given a sample case study to work on that was basically an old Kaggle competition. They asked me to prepare a 30 minute briefing on my findings to present on the interview day. The on site interview consisted of 6 back to back interviews with lunch in the middle. Most of the questions were about my background, why I was interested in the role and what I was looking for. There were no coding or white board sessions.

1st round is with the recruiter. Then they give a case study. Then, a technical round, based on the case. I got ghosted after I completed the case study, which I worked on for hours. rude.
