Although working as an investment banking analyst was a living hell at the time, I now look back at my years with nostalgia. Luckily, as time passes, the 100 hour weeks just blend together and the pain has gone away. Of course, I'm still irrationally uncomfortable and nervous whenever I see a red blinking light (Blackberry email) but other than that, all I remember now are the fun times. The 5am nights when you finally get the pitch books binded and shipped to the MD's house and as you're waiting for the driver to call you and confirm that he delivered it, you're joking around with your associate/VP and realize that they're actually human beings too.
However, the best parts were the office gossip and hilarious stories that were shared among the analyst class. The best stories always came from the summer interns, which made sense because 20-21 year olds know absolutely nothing about anything (including common sense).
One of my favorite stories was a summer intern who had a bad case of diarrhea. Unfortunately for him, my BB was proud of their latest technology upgrade for the entire bullpen, the wireless headset (which of course is about 10 years behind the technology of any normal corporation).
Armed with this technology, he was able to piss off an entire deal team and probably single-handedly kill a deal.
