I applied online through LinkedIn for the interview. Got a call from the HR soon regarding the interview. Since I had attended an interview earlier, I knew about the 4 round that was to be conducted that day. I cleared the first round but could not clear the second. I hope it was not my day so I couldn't clear the 2nd round. I was really impressed by the feedback given by the HR personally to each candidate who was selected or not for the next round. I think most of the companies don't even bother about giving a feedback at all. Keep up the good work HRs. Looking forward to new opportunities.
