One of my closest friends is an investment banker in Cleveland, OH, from what he tells me:
1) The hours suck, he's working 10-12 hours per day minimum
2) The pay sucks, while he is making more than I am, his implicit hourly rate is lower than mine
3) If you stick with it long enough and are performing at a high level, you will be compensated for it with higher salary and better hours.
--- it is getting there is the trick
Hope this helps.
