Pros
The people - the employees (not management) in the London office are an outstanding group. Motivated, passionate and friendly. Benefits - these are generally good with private healthcare, subsidised gym membership etc. Culture - dress down Fridays and cake Fridays are a favourite. People are genuinely friends with each other and pub trips are regular.
Cons
Career progression - was mind-numbingly slow before and now after the recent re-structure is non-existent. Career progression 2 - under the new structure specialising in an area is very difficult. You will be expected to work on different bids in different areas - creating jack of all trades master of none workforce. Pay - DAI are notorious for expecting you to work very hard for next to no money. You can expect to be paid 15-20% more at a competitor for the same job. The management - completely out of touch with employees. They are very stuck in their ways, do not listen to advice/input (even when they ask for it), communicate terribly with the teams and are unwilling to change.
