Pros
Honestly - generally houses very motivated & smart ppl, high prestige (in banking/ finance, not as much now in the popular eye). Work hard & as result can learn lots, good exit opps.
Cons
Expect to work hard, to then work harder, then to work hard at politics, and then to work hard at working hard. High burnout rate. Easily loose sight of bigger picture, no work life balance. Good for ppl who want to hide from life by working all the time. For your overall experience here, you are at the mercy of your manager & ppl you work with - if great you will have good to decent experience. If bad - god be with you, it can get really ugly. Do your research on who you will be working with, if at all possible. If you are spending 60-70+ hrs at work (and this is at job outside of investment banking) being around bad ppl, you will hate life. Also remember, do cost benefit analysis. You do get paid decently, but do your hourly rate math. At the end of the day, it probably isnt as much as you think.
