Colloquio
Applied online and initially had a telephone interview with HR. Followed by 3 rounds of 3 people each round. Very interesting and challenging interviews with a mix of coding, finance and behavioural questions. Very good experience with the interviews. However the HR is one of the worst you will ever have to deal with. I had to chase them to arrange interviews, very unresponsive, they didn’t share details of the interviewers unless I asked multiple times and in a case they send me a request for a same day interview. Of course they never shared any feedback and I didn’t even get a rejection email.

It will be a phone interview first. They will ask you technical questions about probability/ statistics. The interviewer is friendly, but the question is not easy. The process is good.
