The process was exactly as described on the job posting - one HR interview, one team interview, a written task, and a final interview (never got there). HR interview: 15-20min, very friendly, mostly about role expectations and motivations. Team interview: 1h, super friendly and you learn a lot about the job. It was a mix of motivations, skills, and knowledge about due diligence sector. Some questions were not necessarily hard, but required to stay a bit up to date with the news. A written task: classic due diligence exercise you get at other firms. It's quite long at 6h though but you're allowed to do whenever you can. I didn't pass to the next stage but got pretty good and detailed feedback on the written task so it was overall a good experience. The only negative thing I have to say is that between the HR interview and team interview, nearly two months had passed with no contact nor replies to follow ups.

Multiple rounds of interviews. Often weeks/months apart. 3-4 rounds, including writing test, over the span of 4 months. No response/feedback/rejection letter after making it to the final interview, which was at the office and lasted almost 3 hours.
