What is actually insane is the amount of face time and waste due to process and bureaucracy in that 100+ hours.

I was really shocked when I moved from this to Google where all that mattered was the outcome and I did more work in 50h per week...

People in investment banks waste time on most idiotic things. The most drastic example I remember was importance of order of people in the To field in the email (People had to be ordered by their seniority)

There really should be restrictions on how much an intern can actually work. I know in the US, if you work more than 32 hours a week for a full year, you are considered full time for benefits purposes, but if they work you for slightly less than one year you can work as many hours as you want. I recently got an email from my school advertising an internship at $10 and 50 hours a week, right as the new semester is starting.

It's absolutely insane, and the intern's manager should have stopped him from working so much, even if he was never explicitly required to work that much. During my internship, my manager sent me home even if I wanted to work more.
