Pros
Projects contain challenging work that is generally interesting and engaging, usually involving problem solving and creative thinking at its best. Work is is constently changing as projects kick off and complete at various clients across the world. Travel is constent, there are opportunites to travel and work abroad. The firm provides an opportunity to work with some of the brightest minds in the business, masters degrees, MBA's, and PhD's are plentiful. The people at the firm are mostly 'work hard, play hard' types and incredibly driven. Coaching and mentoring are important, management wants employees to succeed as this reflects well on the firm. Travel provides tons of points :).
Cons
Travel is constent, most people are on the road Monday through Thursday and work from home offices on Friday. For some, this is a great perk and for others it can be incredibly intense, cause homesickness and lonliness. Work/life balance can be tough, a lot of effort must be made to maintain contact and relationships at home. There is a lot of pressure to meet deadlines and perfect work is not expected it is a requirement. Mistakes are not tolerated if they are seen by the client. Work is required to be completed on time, perfectly and to client expecations. There is stress and intensity on a daily basis. Overtime is standard.
