Similar experience here. Been watching HN's hiring posts for 6 months or so, replied to many, received about 3 responses. I know I'm no John Carmack, but I've had a $100K+ offer (for a telecommuting position), and have a $100K offer (again, telecommuting) on the table. All these poor companies so desperately trying to hire have never even bothered to investigate if I'm a good candidate.
I'm not too bitter as my opportunities are fine, but it really makes me wonder - are these companies insane? Do they actually want to hire? Do they really think they are amazing enough that nothing less than John Carmack himself is acceptable for them?
