Pros
It is a very dynamic place to work. On one assignment you could be a technical solution architect but if the partner or the engagement manager feels you have potential can give you a much different role in the very next assignment. So, career growth is a possibility if one has the initiative and the ability to lead/deliver to expectations. Client satisfaction is a major priority - so if you are involved in client service, you are in a great position to influence how the rest of the organization provides services to clients. Opportunities exist all around the globe and if one is mobile, can go places, experience different types of clients across industries etc.
Cons
The company needs to focus on improving the work-life balance of its workforce. There are two major components in the business and the ones with Consulting type work, have a very lopsided work-life balance.
