You are apparently in the UK, but the job market in the U.S. has similarly been very spooky lately. I was laid off and have received almost no interviews outside of a single previous employer. My resume was flat out rejected, even from places that I had previously worked or was made an offer from as little as a year or two ago. It was really weird. As in, previous contacts would not even reply to emails or LinkedIn messages. I felt the same thing, thinking things like if I insulted someone's dog or something. I even got contacted by a former company asking if I'd be interested in coming back, and then when I responded, they responded with a flat "we don't see a fit". Just purely bizarre.
I am finding that more and more people are looking for extremely specific and narrow experience. Like, if you haven't used <x> technology and worked in <y> domain, they don't want to even speak to you. They'd almost rather higher a new grad who happened to work in <x> than someone with experience in many languages and domains. It's really weird. I've been thinking a lot about how to make my own path, because it's exhausting trying to apply and work for myopic places.
