Jumbled and slow process which eventually led to an interview with a Senior Consultant from a different department. No preparation at all - I never actually spoke to anyone who could answer any questions about the role. By the end I wasn't actually too interested, which is quite a result considering I'd always wanted to work for a big 4 firm. No proper feedback following a fairly positive interview, other than a generic rejection several weeks later.

I had 3 interviews, 2 technical and followed by partner round, technical round is all about previous experience and your technical ability. First technical round interview was 1 hour and followed management round. Second interview was purely technical on technical.
