I've read on SDN that oftentimes interviewees feel great (or poorly) about their interview performance and are blindsided by a wait-list/rejection decision (or acceptance). 
Can anyone familiar with the interview process comment on why they believe someone's self-rated interview performance might not coincide with the end decision?
