KPMG Manager interview questions

I was scouted through a headhunter, therefore my entire process was very easy - I submitted my CV, got a call from HR to clarify some smaller issues and then was invited to the interviews. All in all I had 2 interviews - one with the department I will be working in and one with HR, 1 hour each. The first interview was in English, the second in German. Overall the experience was very nice, the questions and talks were reasonable and I had sufficient time to ask my own questions as well.

Wasn't the best, as I had applied for the Assistant Manager role only to be interviewed for the Manager role and was told I didn't have the requisite experience. A bit confusing to say the least and bringing this up to the hiring manager yielded no results.
