In my case, the process became so awful, humiliating, and hostile, I just gave up, and retired, ten years before I had planned. I’m very fortunate, that I could afford it. I now develop software for free, for outfits that can’t afford people like me.
It’s tough, but looking for work after 50, especially when pivoting from management, back to IC, is unbearable. My heart goes out to those without the means to walk away. I think some companies missed out, but I am under no illusion that I’m missed. I doubt they had any regrets in passing me up.
In my case, it was probably the best thing that ever happened to me. I left a lot of money on the table, but I have been happier than I ever dreamed, while working twice as hard as I ever did, when I was getting paid for it.
