If I did it again, I would:1. Watch out for the cold/unengaged one (if interviewed by >1 person)... the one who you think might be sizing you up as potential competition rather than interviewing you with the firm's interests at heart. Play to the egos and reassure that one in particular.2. Research who will be interviewing you, and cancel if appropriate. There's no point in wasting your time being interviewed by juniors who are just there for interview technique practice (cynical, I know, but I'm now firmly convinced this is the right thing to do).3. If they ask you questions about skills or experience etc, make it 100% spot on directly the same as exactly what they are looking for - and nothing else. From experience, accountants aren't the best in the world at 'thinking outside of the box' or drawing inferences about 'transferable skills'.4. Remember that PWC is a firm of accountants. My experience is that, however much they yell that they're "consultants", they'll always have an accountant's approach to doing things. i.e. Very report-focused, bitty assignments etc. So, go in there acting like someone who prefers to work in this kind of way.
