This is my first interview after passing a take home test. The interviewer starts by going over your cv, talking about one project that you think is interesting. Next, they ask you 3 stats questions. The length of the interview is 45 minutes

Onsite: potentially have five rounds. The first two rounds are coding and data analysis. I did not pass those, so did not have a chance to go to the stats, open-ended questions, and HR round. The coding questions are actually not difficult, but more like reading and rewriting some classes. Data analysis is also not tough but requires being more familiar with packages. The interviewers are not very interactive.
