The first interview was on campus, 45 minutes. They asked me basic personality questions (who is my role model, what do I look for in a friend, what am I most proud of) and then when I mentioned stats they asked me 2 very simple stats questions (what does R-squared mean, what does a positive slope in a regression mean). After that I heard back almost 2 months later. The next round was 2, 45 minute, online interviews, also only personality based questions. Honestly the whole process was very friendly and relaxed, but also a little vague. I'm not sure what they base their decisions on. Make sure you know your resume very well and be prepared to talk about things in a "STAR" method. Situation, task, action, results. Then if they have questions elaborate on the details.

There were three rounds technical managerial and the last one was kind of hr where they ask you about your current offers and willingness to relocate and some questions regarding the company
