Yep. I switched career fields at 36, stayed for 14 years and then switched career fields again at 50. Still in this new career field but just changed companies in August at 52.
It took me a relatively long time (6 to 9 months) to land this new job. I'm pretty sure my skills weren't where they needed to be as a software developer played more of a part than my age for other companies to not hire me. I had some great interviews but it all worked out. Really happy with the new company.
