This is what working in the Bay Area was like during the bubble, during the recovery and early Web 2.0.

You work 6 and 7 days a week, keep crazy hours, sometimes you duck out when you need to. Long lunches are a thing, you drink at the office. All personal decorum goes to hell. It becomes purely about the work, about doing well.

It's a pressure cooker, a boiler room, it is swimming with sharks. You will either learn to find a deep inner productivity or you will drown. Things get rather wild in this sort of environment. I suspect that addaral is still the drug of choice for this set.

Every one can taste their "fuck you" money and is just looking to hold on long enough to get out.

If your cut out for that sort of game its great. If you arent it's hell.
