I email, inquiring about the position. "Oh, we gave that to someone we had been interviewing for months, but we'll keep you in mind for the future." Unprofessional disconnects and other encounters like this have taken place several times, in my experience. It turns out I knew the person who did get the job I was all but promised. After talking to them, the company had contacted them three days after its last interview with me, and the successful candidate had been asking for $10,000 dollars less and had less experience than myself. A month later, that candidate emailed me and told me they were let go for "being unable to meet the requirements of the position."
Anecdotal experience like this really makes me skeptical when I hear employers bemoaning that they cannot find employees. Can they really not find employees or good talent, or do they just not want to pay the wages that people are asking for?
