Worst experience ever, I have given 3 rounds on 3 different days and on final day, HR person came n told that you are rejected but he was not having answer for my rejection.

At least let us know reason of rejection or else don't take 3 - 4 rounds n waste our time n money.

I personally recommend not to attend interview here.
