This clearly isn't the job for everybody (obviously not Marco), but there are plenty of people out there who are (as the ad puts it) "not terribly money-motivated" and would be willing to work hard to be in a cool environment with cool people. [Some of the best jobs I've had have been for absurdly low salaries, but I don't regret them for a nanosecond...]
Given who wrote the ad, I also wouldn't be surprised if they're exaggerating a wee bit and making it sound rather scarier than it really is. Having a small outfit with reasonable people in charge (and whatever faults they have, I don't think PA are really psychopathic-startup-CEOs in disguise) is one of the best insurances there is against a truly unreasonable work environment. Sugar-coated job ads are an insurance against nothing....
If anything, I'm more disturbed by Marco's rush to judgement...
