After the phone screen, there was standard interview loop. The first interviewer was late to the interview and clearly was frustrated about something which showed up throughout the interview. He was rude and cocky throughout the interview. He was irritated on something, checking his phone in between. He asked me architecture design question and at one point when he didn't get the answer he was looking for, he started telling me how he had designed more complex systems at Amazon and suggested that he was giving all answers for me. After this first interview, I had no interest in the rest of the process or company anymore. I should have left the interview at that point. Couple other interviewers were late - another rude interviewer at the end of the loop. In general, I felt the company culture was toxic and people were stressed. One interviewer in the middle was really good but rest of the process and interviewer just made probably this the worst interview process and worst company for me.
