A lot of people look down on companies that solve 'boring' problems with 'boring' technologies. I guess it's an open question if having been writing in-house CRUD apps using a 10 year old tech stack for several years is a proxy for lack of competence.
I've seen a "senior" developer who didn't recognize what VSCode was. Like, not that they hadn't heard of the specific program—they didn't recognize the sort of program it was.
Not in an interview where maybe they're flustered, this was just an ordinary day on the job. They'd been in strange little enterprise vendor-silo programming environments their entire career. This was accompanied by exactly the sort of lack of understanding of lots of other stuff that you'd expect.
The flip side of this is programmers pushing companies to let them use k8s and Rust and shit when there's not a good business case for it, for fear of having a résumé that eventually starts to look like it could belong to that guy. Not wanting to look like him is a big part of the whole résumé driven development phenomenon.
