Try removing the graduation year and limiting the experience to the last 5 years or so - you'll get much more replies off "cold" channels.
That said, using cold applications being 40+ is generally a bad idea. You need to be actively working on your network and relying on people that know you're good in order to get the foot in the door.
I’ve interviewed at 4 places since, but I’m 0-4. That’s mostly my fault. I never adapted to the new style interviews. I still expect to show my experience and successes and walk out with an offer.
It is absolutely awful that you should have to do this. Starting a new career in web dev at 35 it is something that's on my mind quite often.
More often than not, companies are not serious about hiring, or they are simply fulfilling an interview-to-hire ratio. They are going to behave badly throughout the interview process and sabotage themselves and you over dumb things - even dumber things than ageism. Hiring is absolutely the worst aspect of the tech business, rife with incompetence and lies.
You have to move on and keep hammering away anyhow. Hang in there.
I have had a few companies reply to my applications with an "email interview" questionnaire, but after I reply I usually hear nothing back. One actually scheduled a video interview, but the day before it was to occur, they emailed to say nevermind, the position was filled.
It's so odd. Some of these job descriptions are an exact match for my skill set. I suspect that ageism is a major contributor given that I am over 40. I am starting to look into other industries, but it feels like such a waste to abandon my cultivated experience.
