Initial interview with dev team, interview with senior engineer, interview with HR and senior team leads. Interview process took ~6hrs total (over several days), then was told I'd hear back in a couple days. Didn't hear back for weeks. Not the only interviewer who's had a this experience.

All process went well, organization and people were respectful and polite during interview. I were interviewed by 6 people, 3 of them join company 3-4 months ago. The process of interview between "newcomers" and people who were working there for a while were different. Newcomers were not really interested, and from my perspective were just formally asking questions. Other 3 interviewers were really involved and asking questions and describing their daily jobs. Other nice thing I heard that all of them like to cook. Well, may be that's why I were rejected. There were no real CS/algorithmic questions from technical side. I were asked about traversing tree and writing lazy-seq on clojure. There was no feedback on interview that I'm doing something wrong or I'm giving incorrect answer. Only one thing I definitely failed with was mixing tree-seq and post-walk function in clojure, not sure if it really matters. In conclusion, I think it was just bad moment to join company or may be company has culture agreement that I'm not fit in.
