Avalanche Studios Group interview questions

I had around 4 interviews. 1 with tech director, 1 with producer, a culture fit interview, HR screening call. There's also a code test that requires a good 8+ hours of time

Very tense interview with the QA Manager for no reason from the beginning to the end. I sent a mail to thank the company but I needed to resign from the interview process because it didn't match my expectations. Listed my reasons behind it which were all career-related. Didn't even get an answer.
