Ok guys, figured I'd give a quick update. Thanks to all of you who realized it was a mistake anyone could make! Lately I've been looking for a job, so I have a lot of interviews to keep straight. I had this interview, and another one tomorrow and they are both in the same town, I thought the interview tomorrow was the phone interview, and the one today was in person. Unfortunately I made a mistake, but I've learned to definitely keep my things more organized. The interviewer also completely understood and let me do it in person anyways. Hopefully you all learn from my mistake
