Pros
Strategy practice was hungry. Needed people to step up and lead projects. Great time/place for new recruits to develop leadership. Given ownership of work early on, opportunity to develop new intellectual property and have the work patented. Invited to help sell projects and other work. Time off when required. Travel constantly monday to thursday, but fridays were usually a down day and i spent most of them either golfing or playing play station. I racked up so many frequent flier miles that I've spent the last 2 years away from accenture flying my extended family all around the world, and I still have enough for two first class round the world tickets ... crazy!
Cons
Paid a lot less than traditional strategy houses. Hard to get noticed as a strategy practitioner surrounded by process and IT consultants. Also graded against process and IT consultants in promotion ranking even though you do very different work. always struggling to justify to other people why strategy people get paid more. always the same excuse why they can not pay you more "we have every consultant or manager in a band and you are at the top end of it". Puh - lease! they also price work below competition, so while your friends at McKinsey are staying at the Four Seasons, you will be staying at the marriott courtyard
