Probably an unpopular opinion but I don’t see the issue with this at all. The language implies the ecosystem which can imply much more about the tech stack, and why not just ask for people with experience in it instead of masking it behind some veil of “we are language agnostic”? On the point of soft skills, idk I have never read and trusted what is in listings for those as much as I do technical details. It’s the human part, and humans are insane and complex and rarely ever work perfectly well together. Just probe it on your first call (and subsequent interviews) to get as good of an idea as you can, but it’s still a crap shoot.
