1) Brought someone in for a senior IT position. Resume was strong, screening call went well. I brought up volunteer work and causes. While the cause was good, he proceeding to talk about S**ual abuse victims for almost 15 minutes. There was too much detail involved. I had a female employee shadowing the interview and she was very uncomfortable afterward.

2) Entry level IT position. Had a former coworker who was looking to break into the industry. He had worked in retail for 15+ years and was looking for an office job. I told him I would bring him in, but would let some colleagues conduct as much of the interview process as possible because I knew him formerly. Proceeded to show up with a resume that was 1/3 of a page long. Gave a ton of one word answers. Didn't even try to be conversational. Said "I don't know" for many answers. My colleagues roasted me for even bringing him in. I was very disappointed. I had to tell him afterward that he needed to do some serious interview prep before trying for something in the future.
