There were 3 phases. First with 2 HR girls, where questions were about games in general and self descriptive ones. Second phase was with 2 data scientists, where there was 3 types of questions: Algorithmic thinking, statistics and data set exploration. The last phase, with team leader, where we were discussing about Data science in general, about Machine learning, how algorithms work and things like that.

The hiring process consisted of three interviews split into two rounds taking 1.5 hours each. The first round started off with an HR interview followed by a technical interview. The second round was solely a technical one. The interviewers were kind and friendly and they helped me overcome my initial nervousness as well as any obstacle I came upon while I was going through the interview questions. The interview questions were something you've come to expect in an IT company - algorithmic problem solving, probability calculus and brain teasers. I received a job offer a week after the last interview.
