The initial interview process was as expected. First was an online coding round, then an assignment. Followed by two more technical interview rounds. While some interviewers were normal, I found some of them were pretty rude. Specially the last hiring manager round. The guy was straight off pissed about something, and he was taking it out on me. He was just very unprofessional. It just showed that the work environment would be so toxic at-least in that hiring manager's team. I would suggest to teach some basic courtesy to the people representing your company.
