Well, actually I’m in the process of retraining now, and as I understand it people over a certain age are persona non grata no matter how well they kick the ass of the rest of their graduating class!
I got laid off from a pharma sales job after 27 years in 2011. I was retired for 1.5 years, then decided to try to get back into pharma sales, and let me tell you, when you are pushing 60, it was like playing the devil to get hired. They are not looking for somebody pushing 60, but rather for good looking 35 years olds! I eventually did get hired and have been with my current company for almost 3 years.
I hope you get a job that has some ties to your previous career so that you can leverage both knowledge and experience.
