Not necessarily. Luck of the draw probably. Its much easier to get accepted earlier than later due to obvious reasons. So individuals with lesser stats/credentials that interview early almost guarantee their acceptance. I interviewed at 4 schools early and got all 4 acceptances. This was my only "late" or later interview. How people get chosen before others... well I do not think there is any rhyme or reason as some would say.
I agree. I regret getting my application in a little late here--I interviewed on 2/1 so not much before you. After getting myself worked up today, there ended up not being any mail from PCOM--I guess another day of stress/anxiety is in store.
