I was approached by a recruiter who found me on LinkedIn and had several conversations with him and submitted an online application directly to the Charlotte office. When invited to the office, I waited 30 minutes past my scheduled interview time (which I showed up 15 minutes early for) before asking someone what was going on. I was brought to the hiring manager's office where she told me she forgot, apologized, but then given a rushed 5 minute Q&A session and told I'd be contacted in a couple days. I told them not to waste their time.
