It was very standard with online assessment then a phone call. Im sure there were other rounds but I didnt pass the first phone interview. 3 Questions for the first phone call. Two probability and one brainteaser. For probability just review Bayes and know how to do linear equations.

Two rounds of phone interviews, the first lasting 45 minutes, the second one hour. Interviews began with a couple of behavioural/motivational questions and then moved to small quantitative problems. The questions are very similar to the ones you can find on Glassdoor. Be sure you know bayes formula and are comfortable with clearly explaining solutions on the phone. Interviewers were very nice and helpful. Unfortunately didn't make to final round even if answered to all the quantitative questions.
