I am of course not asking about those "Would you like to join my team" job-postings disguised as questions which appear from time to time, but rather about generalized questions about where and how to hire developers, artists or other team members for a game development project.
The help center lists as on-topic questions, among others:
- project management (testing, team management, scheduling, publishing, etc)
Assembling a project team is the first part of team management.
One recent question which was closed as off-topic through a moderator was "Where can I find animators to create 3D models and animations for characters in 2d isometric game?" but I don't want to discuss this particular question but rather the issue in general.
Assuming that a question asks about recruitment strategy for a game development project and that it does address aspects specific to game development which don't apply to general software development (which would make it more fitting for programmers) or even hiring personel in general (which would fit on workplace), could the question be on-topic?
