Revolut Data Scientist interview questions

I just talked with one person. He was very unpolite. The worst interview that I had so far. He asked questions that don't make sense for the position and he was very unpolite about the answers. I am greatful that I don't have to work for this company.

There were three rounds 1. Live coding round 2. ML 1 Round (Probability , Stats & ML Algorithms) 3. ML2 Round (Domain Specific) I found the first two round were very nice, the interview was interactive , but the last round the interviewer was acting like an AI bot, They expect you to know everything even for junior or mid level role. I don't understand if a candidate knows everything , what is this organization offering in terms of learning.
