Screening with a recruiter, two interviews with members of a team that you select, one is a classic behavior, the other basically discusses technical information of a company you research, finally, there is a 4.5 hour "simulation" case study thing which is different but not too difficult and also includes submitting a couple take-home assignments before-hand. Everyone was very nice, the interview process was clear and the team/recruiter was very communicative. The process did take a decent amount of time preparing for technical/completing take-home assignments and the 4.5 hr day. At the end of the process, recruiter told me they were freezing hiring for this position, wish they would have told me before putting in all the work but still a good experience.

First round was a 20 minute PowerPoint presentation of a case you are given beforehand. The interviewers interrupt to ask questions and that may mess with the flow of the presentation. They ask about the maths, the solutions provided, and your thought process. They also ask about personal experience but it takes less time than the presentation
