I once had a job interview for an HR Department of a large company. I think it would have been a great job. The thing was that I think a previous boss might have torpedoed me. I have no way of knowing for sure. But I do know that I didn't get it and that something happened when working with her that was a big problem.
I was accused of saying something about someone that I didn't even know! When it came up and I denied knowing, my boss didn't believe me. Funny thing is she didn't even say what it was, so to this day I still don't know what it was. It came down to her not believing that I could handle confidential information.
Because I was concerned about this, I had a friend call her and pretended to be looking into hiring me. I thought I might be safe. Since my previous boss had worked in HR, I thought she would potentially refrain saying something that could be problematic, but I was wrong. If my friend had been a potential employer, there is no way I could have gotten that job.
I am not sure what issue that boss had with me. But there were other issues at other times, too. When I was intending to leave Columbus, the way I had to do it, I wasn't going to be able to give notice. I wasn't really too sad about it. And it was, quite frankly, a huge relief to get out of there.
