Just because you have "25 years in the business with 15+ in psych, including four antipsychotics," doesn't mean you were the best candidate, and it also doesn't mean you are not a great candidate. With that type of experience, you most likely got the invite for the interview because of it, but somewhere in the process, you were beaten out. However, these positions were highly competitive, so perhaps you had a bad day at the interviews, and your competition was a better fit. It happened to me...I am solid at the same experience level on paper, and a few Pclub wins are scattered throughout my history. I just found out who got the position I was going for, and they are fantastic, so they had several great candidates to choose from. Happens, so on to the next opportunity.
