Colloquio
HR cold-calls and does the profile verification and lets me know that they are looking for a Data Scientist urgently as part of their Analytics team.
I gave them a set of dates that I would be willing to take the call for the telephonic technical round and henceforth asked them to confirm once they talk to the hiring manager.
No intimation, no email confirmation, no phone call confirmation.
The hiring person went on with the technical round after 2 days.
My technical round too was more or less a cold-call. I did let my interviewer know that there was no intimation regarding this but they just gave a deaf ear to my words and told me that I will get to hear from somebody from their team.
As expected, got the reject mail the following day.
My advice : If the hiring team hasn't sent a confirmation for interview and you still go ahead and make a cold-call for a technical round, yet if somebody puts up a decent show and you reject them, you know you're hiring method is wrong and you better change.

Colloquio
Started out good but ended as a very bad experience (WASTE OF TIME). I had 5 rounds with 1 being HR screening round and 4 technical rounds after which I was rejected without any feedback. All of them were pretty good and the interviewer was happy at my answers. Upon asking for feedback multiple times, the HR just turned blind eye and never responded with the exact reason.
After 4 rounds, the HR did not even call to reject you. It was just via email without any specific reason.

Domanda 1
Round 1: Basic profile matching round and getting expectations from both sides
Round 2 and 3 were purely of data science and machine learning fundamentals. I enjoyed as they were more like a generic chat among data scientists.
Round 4 was system design/ engineering round where some fundamental questions were asked.
