I applied for an internal job, and the hiring manager told my manager. Eventually I found out, and was chatting with the hiring manager and casually brought it up (in a totally non accusatory way). He said in the company he was in previously, this is normal. And that he found out recently that it is not normal in our company.
Is it normal, in your company, for the hiring manager to let the candidate’s manager know they are applying? The hiring manager has many years of experience.
