Deloitte Tax Associate interview questions

First was an phone call with the HR asking about basic questions regarding my previous job and experience. Second round was aptitude and Communication skills. Third and fourth were technical rounds. Final was with the HR and the you get the offer!!

I made a great mistake. I came 10mins late to my interview. But it didn't start until about 4hours later. The interview lasted about 1hrs and my qualification where right. I think I was not given an offer because I came late and I was an engineering graduate applying to be a tax associate.
