It seems to be a part of popular folklore that those in Investment Banking spend 100+ hours a week at work in the office - at least on some occasions. Having spent the last few years in the corporate world, I have often wondered how a 100 hour week in office must feel like.
A 60 hour work week is very different from a 50 hour work week. Somehow it feels a lot more than the 20% increase that it sounds like. If you are working 5 days a week, suddenly your leisurely 9am-7pm work days must now expand to 9am-9pm days - each day of the work week. I am talking in-office hours (discounting working remotely etc), and somehow that feels very different :)
Last week started as one of those weeks which at the outset sounded like it would be a somewhat tiring 60 hour work week. As the week dragged on, days inched up to 13 and then 14 hours. All of a sudden, 12 hour days started to sound like sweet luxury. Friday was not much better. Throw in a few hours on Saturday and a 'light' 10-hour Sunday, and that made up for my first 80 hour work week in professional life. Very reminiscent of the last week every semester during college and grad school.
Somehow though, work doesn't feel that tiring when you are enjoying it. The hours just go by. Days and weeks fly past as if you are on a swift conveyer belt. The real fallout however is the drastically reduced amount of time that you have for anything else - including family, friends and hobbies.
Now I *really* wonder how the IB dudes and gals clock those centuries on a regular basis while maintaining their sanity..
