Twitch Senior Software Engineer interview questions

A Twitch recruiter reached out to me. Following that, I had a call with her. Then, I had a one hour long call with the hiring manager, where he mostly went over my experience, etc. No technical questions as such. After this, I had my virtual on-site round, consisting of 5 one hour long interviews. There are two coding rounds, one soft skills round and 2 architecture rounds. Remember that they will ask you behavioral questions (based on the leadership principles, etc.) IN EVERY ROUND, not just the soft skills round. When it came to my soft skills round, the interviewer thought it would be appropriate to turn that into an architecture round as well. So, in all, I had 2 coding and 3 architecture rounds (which I was not informed about in the pre interview calls), with behavioral questions spread across every round. The thing I was the most disappointed (and angered) about was that when I asked the recruiter for feedback regarding my interview and what my shortcomings were (so that I could improve them in the future), they said "We do not provide any feedback to the candidate". I mean, wtf is this behavior? This is the most condescending a company has ever been to me. I'd never in my life apply to Twitch again. The least you can do after rejecting a candidate is give them some feedback, so that it helps them. Absolutely horrible experience.
