So I interned at a place for a year. I did good work (I thought at least) and left on good terms with everyone I regularly contacted. Problem is, I've been trying to get a job from there for months and I can't land a single interview and none of my former supervisors will return any of my attempts to contact them. The place's HR office is close by and would be responsible for selecting and interviewing me.
Should I talk to HR or not bother? I doubt it'd help anything but maybe it could at least give me closure.
If they didn't offer you a position after you ended your internship, they're probably not interested in hiring you. At the very least, there probably aren't any positions going there - they can't give you a job if they don't have a job to give you. It can't hurt to contact HR, but don't hold your breath.
