I have encountered the same problem but as a FE engineer who doesn’t do backend. (we should hang out)

I think some shops just really want everyone to be interchangeable as a way of ensuring no one becomes too niche and therefore irreplaceable. i.e. it’s a control thing.

My suggestion would be to look for info early on in the vetting process for stuff like how titles work there and how teams are organized. possibly ask to talk with other potential teammates or other employees.
