Still, finding a job where my boss would know more is more and more problematic.
When I was 33 I was rejected by a recruiter with "you know, here I have dozens of resumes of people 10 years younger than you, who have lots of experience in managing teams. There must be something wrong with you, so I cannot pass your papers to the client."
Still, looking for a job is a very traumatic experience. The companies are looking for unicorns: young, cheap, without family (aka drinking in evenings, working on weekends), with lots of experience, and academic knowledge (which will never be used).
A couple of times I heard from guys, who would be my managers "oh, I'd love to have your experience"... the rest of the interviews went smoothly. In all the places I even didn't get to the step where they asked for the money requirements. They just didn't answer.
I'm looking for a remote job now. I even made a nicely stripped resume on one page. My normal has 3 pages. It's a very traumatic experience, especially that most of the remote companies require knowing almost only some new stuff, totally ignoring my 18 years of experience in everything else.
Btw... a surgeon of my age is usually not experienced enough to make surgeries on his/her own. A programmer of my age is usually a useless resource, which is happily replaced with someone just after the college.
All this makes me sad. The experience is not valued here. So what is? The lack of experience?
