40+ hours in a office where you sit at a desk and type, fill out reports, etc.
If only it sounds that easy. Usually you get a project where you sit your ass on the desk stare at the monitor for 8 hours straight for few days. Titu is dead on the money, don't try to rush or anything. What I did was I try to be like superman, since I just begin to work. I barely took any breaks and just typing and working like crazy, that shit burn you out like hell. Don't try shits like that.
If you want to compare working hours, don't come knocking over here. A normal work day for me is 12 hours. During hurricaine season, when a storm makes landfall and causes a lot of power outages and structural damage, I'll be working 16 hour days, 7 days a week until everything is fixed. Last year, I had almost 4 months straight like that. The pay is RIDICULOUS during that time, which is the only motivation to keep going.
