I had a first round interview with 2 people via a recruitment agency, interview went very well with nice interviewers. After the interview the agency said they really liked me and wanted to arrange a second interview and he would get back to me with availability, but I have never heard anything since. I did not receive any constructive feedback, just that they really liked me and I have no clue as to what happened with the second interview they wanted. I would have liked to receive feedback even if they didn't take me through to the next interview stage.
