I was rejected from 2 Corporate Captain positions (Citation VII and CJ2) for being too young. I met all their other requirements, was contacted on a couple of occasions for phone interviews but was told they were looking for someone older (35-45). I was told many VIPs want their pilots to be older. This came from two different operators. "Good resume, too bad you're not 5-6 years older!" Companies know what they want. It sucks when that rules you out, but that's the way it is. The quicker you move on the better.

PS- I eventually found a much better job. Things happen for a reason.
