Im 42 and just started my first tech job as a UX developer (bit of both), after 4 year degree. I had concerns that my age would be a hurdle. I won’t lie, there are some companies that will not think you are the right ‘cultural’ fit, i.e., the cool, funky start-ups. That said, if you get lots of CVs away something will happen. It did for me. The first company that took the time to interview me hired me straight away. Hang in there.
