I had a positive initial conversation with the recruiter, who was helpful in setting up the technical interview. Unfortunately, the technical interview itself was a disappointing experience. The interviewer seemed to be following a very fixed script and appeared to have little flexibility in how answers were evaluated. It did not feel like candidates were rewarded for explaining their reasoning, making reasonable progress, or demonstrating practical understanding.
Several questions felt overly niche or poorly calibrated relative to the preparation material provided. The interview seemed more focused on whether I produced a very specific expected answer than on whether I could think clearly through technical problems. As a result, the process did not leave me with confidence that the interview was assessing the skills actually needed for the role.
I also left with a somewhat uninspiring impression of the work. Based on how the interviewer described the role, it sounded less intellectually engaging than I had expected. In the end, I was not disappointed to leave the process.
Got asked some brain teasers and stats questions. Kind of hard especially starting with a brain teaser that you won't expect in a "stats/data analysis" interview. The interviewer was nice though.

There are 5 rounds of interview. They test you on different subjects, statistics, ML, probability, algorithm. The process is a bit frustrating, but very interesting in general. Seems they have professional team.
