Tinkoff Credit Systems Bank interview questions

I was given a couple of coding questions during the Skype conference call. My screen was shared and there were 4 or 5 employees. I had to write a compilable piece of code (that means, I had to remember the exact names of the functions) in 2 hours. I'm not into interviews like that, but my interviewers seemed to forget that the interview is a double-sided road. I was told I'm not allowed to ask ANY questions at all because "it was them who interviewed me and not the other way round" (this was a huge red flag for me). I guess I shoud've finished the call after 10 minutes when the interviewers started being pretty rude to me. I should note the HR-manager who guided me through the process was a very nice person and they felt bad it didn't work.

About 2-3 technical interviews combined with motivation interview. First interview is group one. You have to answer general logic and math questions. Second (third) interview is individual. Specialists from an applying department ask questions about your qualification, skills, university.
