Pros
The people you work with and the constantly changing environment, creates an exciting and challenging environment to work in where the next good idea can come from anyone at any time. Your clients are some of the more interesting and significant businesses and so present varied and new challenges frequently. Further through your training and the stature of PwC you are respected by your clients as a trusted advisor and source of information. The opportunity to influence or change your career always exists althogh sometimes it can be more challenging to achieve this than others there is usually a way if you have a particular goal/ambition in mind.
Cons
The hours, busy season can be a long period and you have little opportunity for vacation in these periods, so forget that skiing hobby because Jan - Mar is a no go area for most people.
