I gave my resume to a Microsoft recruiter at a presentation at my university. A week or two later, I received an email from another recruiter. They stated they would like me to come in for an on-campus interview and asked for a quick response so they could schedule it. I responded immediately and provided my availability, which ended up being only one day. Then, I heard nothing until noon on that day, when they asked if I could come in at 2 PM.

I had given up on the interview by then, but I agreed to come in even though I was unprepared. The interviewer asked me one question about linked lists. He seemed almost as unprepared for interviewing as I was, and the interview lasted only about 20 minutes. By the end of it, we both knew it wasn't going anywhere.

Copy a linked list variation.
