When we had our opening in August of last year, my publisher told me to move quickly before the higher-ups in corporate changed their minds and cut the position they had just approved. I had some candidates within a couple of weeks and flew someone in for an interview in early September. For various reasons above my pay grade it wound up being late October before we formally offered him the job. Even though I had told him he was the guy for six weeks, it wasn't surprising when he turned it down.
I don't blame him, but it put us back at square one in the search process. All of the resumé leads and job ads had gone cold in those six weeks. I didn't want to keep interviewing people when there wasn't a job to offer, and if there was one then we had our guy in mind. I certainly didn't want to spend money and political capital on flying people in to interview in that situation.
We finally found somebody in December, a recent college grad,. He started in January, 4 1/2 months after that whole ordeal started -- and he got laid off in July, which was another level of ridiculousness.
By the end of the hiring process, though, I was ready to hire anybody with a pulse just to get it over with and get somebody on board.
