Colloquio
I did a Zoom interview.
The interveiwer was kind and asked me some probability questions.
I stumbled a bit but answered correctly in the end. However, I didn't get an offer so maybe they want someone who answers straight away.

Technical interview round 1 and 2. Two math problems/brain teasers. Round 1 is easy, but round 2 becomes more challenging. Problems are well designed with multiple follow ups. Interviewer super friendly and nice. Great people and nice culture.

Colloquio
Very friendly interviewer and relatively easy questions. Quite organised in their interview process, with clear guidelines as to how to approach the interview. Focus is to explain the rationale and not just get the correct answer.
