For an ok place, $125k. For a cool place $115k. If there's the expectation of off-hours support, add at least $10k. That said, I'm actively looking. I suppose the numbers would be higher if I weren't.
Thanks for all the responses. I thought of one other thing I'd like feedback on: When it comes to salary negotiations, do people ask for signing bonuses these days?
I really like your question about the impact if they can't fill the position. It seems like a tough one to get away with, though. It could come off as too cocky, or as too much of a salary negotiation setup. Does this one go over ok? What kinds of responses have you gotten?
Also, on feedback: have you ever gotten useful feedback from an interview that didn't result in an offer? I've tried, but rarely gotten anything, and even then it was so vague as to not really be useful.
