I was doing exactly opposite (Angular-only) but now I see that maybe times when there were plenty of Angular positions with often more interesting projects are gone
Yeah. Around 2019 most companies I interviewed for started telling me they're rewriting their Angular projects to React. Before that there was a good number of Angular projects, but I'm seeing only React since then, occasionally some Angular maintenance when it's not worth it to rewrite (so you don't really want to work there usually).
