Had a job interview with what seemed to be a recruiter or with someone fro HR. He was a nice guy but clearly didn't know how to calculate salaries. In the end I received an offer but when I put on mail what was discussed, he was very rude like it was my fault he calculated wrong.

One phone interview with HR ( it took 40 minutes) One phone interview with the hiring manager and a unit leader (it took 40 minutes) One on site interview with the hiring manager One on site interview with a unit leader
