I messed up epically on an interview. It was a 3 part interview for a JS/RoR coder. 1. I passed the resume and chat portion 2. I passed the telephone questionnaire and got along great with the interviewer 3. (Fail) I scheduled my interview on a Friday at 4:30pm and there is a 30 min travel time. I left 1hr early...still it was Memorial Day weekend, so I thought the streets would be quicker than the freeway since it was at a stand still. I was so stressed that I literally had an anxiety attack and couldn't even find the address. Never happened to me before, so I'll never forget it.
