I gave my resume to a Microsoft recruiter at a presentation at my university. I got an email from another recruiter a week or two later. They said that they'd 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 gave my availability (which ended up being only one day), and then never heard from them until NOON OF 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, but he seemed almost as unprepared for interviewing as me, and the interview lasted only about 20 minutes. By the end of it, we both knew it wasn't going anywhere.
