All good points, but can we really afford to be picky when we're job hunting in this economy?
I do suppose a better listing leads to better applicants.
I think it's always important to be picky. I have taken jobs in desperation before and they've always turned out poorly. In my mind, it's not worth the cost to be too open and take jobs that are obviously bad matches; it just results in a lot of emotional and mental anguish, until you finally make yourself quit, and then you're back on the street. It's better just to keep looking until you find something that works.
True, unless you can't pay your bills. I took my job before last in that situation. It was for a C# job maintaining a legacy app for $45k/yr. We were literally selling stuff to pay our bills at that point, so I had to take it. It turned out to be a great job with a great employer. I left to join a startup but then back a year later when they offered me a 50% salary increase to come back.
The 'sell my stuff to pay bills' phase was during the height of the meltdown; I was literally applying for janitorial jobs we were so desperate at that point.
