Introductory call with HR - OK. But for some reason, he asked me to provide him with a couple of contacts from my previous employers, even though he could have collected feedback himself. After all, that's his job. Technical interview - I had a good chat with their engineer, although he was quite stifling at times. Interview with managers - just awful, I've never met such jerks before. It seems they decided to show themselves in the worst possible light from the very beginning. They behaved like complete jerks. I was left with a heavy impression and an unpleasant feeling from communicating with these people.
