Obviously the current situation is crazy, but part of the issue is that the specific asks for a particular developer job are dependent on 1) the stack in use and 2) the org chart at that company. 1 is obvious: if you need JS devs, most hiring managers won't want to hire Pascal devs and hope they figure it out. We can question the wisdom of this, but it is the reality. 2 is less obvious but not super obscure. Depending on how you structure your teams, similar positions at different companies might require more full-stack knowledge, or better people skills, or something else. IME there is little to no standardization here for developer roles, especially compared to something like HR or Accounts Payable, or even very similar IT-adjacent industries like game development. Fix both of these issues and we would be able to have something more like a formal apprentice/journeyman/master system for various classes of software developer. As it is, each role actually is pretty much totally unique, at least compared to similar roles in other companies (there tends to be more standardization within the same company).
