Will it be admission suicide to reschedule an interview? I just committed to my 4th choice...then got an email invite to my 3rd choice for the same day/time...
I wouldn't consider it admission "suicide" due to the fact that you could reschedule it based upon personal reasons. It's not like the programs will know that you decided to reschedule due to another interview. However, it may hurt your chances if others make it through the interview first and are accepted.
