How is investment banking?

<p>Is the first few years of ibanking really like going through hell? Do you have to work like 12 hours a day and take a lot of crap from your superiors as described in "Monkey Business." Is there any truth to that and how hard is it to advance/change your career if you majored in finance or other business related field?</p>

<p>alot more than 12 hours a day =X</p>
