I responded online and the recruiter invited me for an interview. However, instead of the same recruiter, there was a completely different person at the interview and it wasn't mentioned anywhere in the invitation email. It was an extremely awful and unprofessional interview, the interviewer was constantly distracted by things like the phone ringing or someone coming in, got up from his laptop and left, came back and apologized. I didn't like the way the questions were asked, as if they were mocking and trying to humiliate the interviewee. At the end of the interview, I was wished "Good luck" and disconnected.
