2 stages interview process. 1 stage with 2 dev-teams, mostly java & Spring related questions + simple 5min coding session. 2 stage FIT interview with team lead and cluster lead - mostly about motivation

I get invitation from HR to discuss "Senior Developer" position. We had phone call and after it i had been invited to 1,5 hour tech interview via Skype. On scheduled date and time, i connected to interview group. An interviewer was too rude and offensive, and after first mistake in my answers he asked me to finish an interview. It was not my best expirience. I think this way of interviewing is wrong and offensive.
