Interviewed for problem management consultant. They took 4 rounds of interview and it went well. Got positive feedback from every interviewer. I was asked how soon can I join. After a round with VP (who was very positive ) there was no update from HR. When I called her, I was given some vague reason for not getting selected. I asked for a feedback from interviewers but no response. Unfortunately we have email id of HR only and she doesn’t reply for feedback .
