In my experience the only way to fight age discrimination is to reach out to ex-colleagues. I sent my otherwise great resume to many companies without any callback, but I didn't want to ask my friends for help as I wanted to do it alone. After talking to my colleague, who said ,,Oh sure, just tell me which companies you want to interview to, my wife works at Facebook anyways'', I was hired instantly.
