Last minute advice on FT position in Deloitte S&O

Hi,

I'm just finished a Masters in strategy and I'm about to start a FT position in Deloitte S&O (Strategy and Operations) in a European office.

Is there anything I should be revising or reading up on before heading in next week? (Other than general business news of course).

Also what skills do you think are essential starting off and what are the ones you picked up after a few weeks/months on the job? Just curious to see what people's response are!

Thanks in advance.
