If you know you hate it, I highly recommend finding a new job sooner than later. I did it last summer and it's just not good for humans (or at least "us") to work like that. Then again, people supposedly actually go for those hacker apartment setups, where someone pays for 5 dudes to live together. Shudder, but there's no accounting for taste. Like you say, it's probably best brought up in the interview.
Already actively looking, but thanks for the advice. If you're straight out of college with no other realities in place, it may be doable, otherwise it's just a stupid waste of an already too short life.
