If I refer a friend/colleague for a job opening, how much can I share with them beyond what's in the public job description?
Obviously, no trade secrets or IP. What about the job "family" information from the intranet for that position? Details on team size/structure? Organizational history? More detailed information on the technical stack?
As a candidate, I would ask questions about all of these things. Even trying to find out before the interview. But, I'm trying to help my friend be more competitive.
