Pros
- enormous prestige / CV - name on the street, sell-side coverage - work life balance - less pressure at the beginning of your career - no sell side manners, people very nice / open / helpful - also a lot depends on in which PMG team you end up and how they treat / train junior PMs, and whether they let you do only some middle office work or actually take risk (in my case was few months of grunt work, then risk taking with small limits and mentoring by senior PMs)
Cons
- real money attitude mostly, sometimes with longer investment horizon (depending on the asset class), but basically if you want to do intraday trading BlackRock is not a place to go - pay is smaller compared to sell side, at least at the beginning, later on it is highly skewed to seniors / team CIOs who are performing the best
