We're currently in the process of hiring candidates for a software development position. The company is small, and the interviews are for trainee level position, for which we're seeking candidates who are either freshers or who have only a bit of relevant experience. That's why little filtering of résumés is done, and most of the candidates are called for an in-person interview.
I am tasked with interviewing candidates at this point. If there are any good ones but I find but are such that they're not an immediate yes/no, then I have a discussion with my boss before hiring. And I am a technical person, not HR.
I interviewed such a candidate, and he had a good résumé, but the interview didn't go as well. I had a review of him with my boss but the latter said that the candidate didn't have some needed skills, so he got rejected.
The candidate called up unexpectedly two days later to inquire about the results of his interview. Since I was not prepared to answer at that moment and didn't want to tell him he wasn't selected(a situation similar to a candidate asking at the end of the interview how he did), I told him someone would be contacting him later to let him know.
I know saying that is the de facto standard response given to a candidate, but I don't really know what I should be telling him if he were to call again. Should I be taking any more steps to tell him the result or not do anything at all and hope he gets the hint?
