KPMG Audit Associate interview questions

Classic one on one interview which lasted slightly less than an hour. Interview was with a senior in the audit financial services department, and it was more of a conversation than an interview. Rather relaxed interview but very directed to what the requirement was, for an interview. I felt quite comfortable with the interviewer, which is a good sign.

Walk in interview process. First there was an aptitude test of 30 questions. Accounting basics and some analytical questions. Followed by 3 to 4 rounds with managers, head of that department and HR. Later they said I was highly qualified for this role and they would move me to advisory. Yet to hear from them. Do not completely understand why they go ahead of the multiple rounds ahead of profile screening. Not sure if overqualified is just an excuse or they genuinely feel so.
