Pros
Markets itself as the "friendly, collaborative" and does, in part, live up to this. Some people you work with are truly great and supportive. There are good projects out there, but can difficult to find/be resourced onto. Good name for the CV and the graduate program is held in quite high regard.
Cons
Obsession with producing (often meaningless) 'internal work', very outdated performance appraisal cycle (filling in a form every 6 months) which leads to ticking boxes rather than aiming to provide excellent work to the client. The company is growing well, but at the expense of it's culture. Low level consulting work is being forced down to all grades as a result. Some management members are terrible, completely focussed on their own bonuses rather than helping their employees.
