Doubftul. I was 40 when I was looking a couple years back and had a better conversion rate of application -> interview than I've had in my entire life. This is for Rails/React work. I had 15 interviews out of maybe 25 or so applications, had a few opportunities I turned down and landed perhaps the best job I ever had.
I'm beginning to look again at 42 and got 5 interviews in the first week and turned down at least at least 3x as many ops that I didn't like because I'm rather picky.
Are there companies that are pushing my resume to the side because they can glean my age by work history and graduation year? Perhaps.
What I will say though is your experience matches much of what I saw circa 2001 during the .com upheaval. I applied to 50 companies in the first month after the startup I was at blew up at, not a single interview. I was 25 at the time though. I knew many people in their 20s who gave up trying to get work.
I imagine looking for work in 2009 was a whole heckuva lot like 2001 depending on what field you were in.
