It is a very thorough process with several stages: call, hacker rank, technical interview, case study, technical presentation, and interview by partners. The recruiter was very attentive, informative, and helpful.

Colloquio
I applied online. CV screen -> online coding -> 1 'past tech experience' interview; 1 DSy case interview + Personal Experience -> 2x case study + personal experience. The process took about 2 months, though I wasn't in a rush + there was Easter, if I was in a rush, probably doable in a month. Everyone was super friendly and helpful, no trick questions.

Online coding: Imo the most difficult part of the process due to some awkward wording. Also a very quick fire exercise, essentially run out of time. 3 parts: SQL, Python, generic ML knowledge. Past tech experience: just make sure that you know what you did and why (may require brushing up on DS knowledge). Tech case interview: 'This is a problem, how would you build a DS model around it', from there a rather normal case. Personal Experience: same as for generalist consultant Final case + personal experience: same as for generalist.

Colloquio
Online test > interviews. There was some presentation part but I did not get to do that as they stopped hiring altogether. I'm not quite sure that they have any idea on how to do recruiting.

I was approached on LinkedIn for a Sr Data Science role. The recruiter seemed to know little to nothing about data science. The process was very messy and there was so much delays often with no updates. Halfway through the interviews, I was told that the office I was interviewing for was not hiring and was redirected to apply for a role in Asia. I told the Asia team I wasn't interested in other locations.
