Maybe I'm thinking about this from the perspective of a young, single guy. I would not move to Crystal City for any job, definitely not with a horde of other young, single men. The number of young, college-graduate women there must be way too small.
That's certainly a fair perspective that I can't argue with at all. I can't guess on specific #s but I'd bet there are lots of single men that would though at the chance of snagging an Amazon job. That number is probably relatively high and would make you a part of the outlier group. Working for Amazon might have stigma on HN but I think generally people have a great impression of them and would love to work for them.
Oh, I completely agree that there are many, many worse places to work than Amazon. I realize I am very fortunate to be able to decline such a job and be able to find good offers at a place of my choosing.
