Pretty much no other industry obsesses as the IT industry over things like job interview process, salary comparison and compensation.
Also, I take it very cautious when switching jobs. Google says that missing on a good hire is better proceeding with a bad hire. Similarly, I prefer to apply to and interview with a few companies at the time, and do my best at making sure I'm making a good choice. I'd prefer to miss on a good company that to end up in a shitty one.
IT is not body rental, I would actually be suspicious of a company hiring me too fast: why are they so desperate? What did drove them to such desperation? Did the previous people leave? Why? Is that bad technology? Bad management? Company-wide unwillingness to fix long-standing problems?
