No need to stress the UCI interview whatsoever, its very laid back; i think they realize their competing with other UCs, so they try to make it as stress free as possible.
they interview twice a month, so expect groups of around 40.
morning opens i with snacks and coffee, followed three or four presentations. on our day we had the admissions lady, a financial aid presentation, an MD/MBA presentation, a talk from the associate dean of admissions and, something else i can't remember...all this takes you to about noon.
at this point you have lunch and the student interviews are right after lunch. Very laid back, they have your UC primary, but not your scores or gpa...so you mostly discuss the varoius activities you wrote about.
then most students get a shuttle down to the uc irvine medical center, about 20 mins away, to interview with your faculity; again, very laid back, my interview had zero ethical questions, we spoke about some activities, and the rest of the time he basically recruited.
and your basically done by around 3.
good luck, and don't worry too much, UCI accepts a lot of the students they interview...there is suppose to be heavy movement late in the season as UCLA, UCSF and UCSD select their classes (even our tour guide admitted UCI was the UC bottom feeder)
again, best of luck
p.s. to the OP, at 38 is great, i have a hard time believing you didn't get in anywhere....a 3.4 is well within 1 sd of most schools...
did you only apply to UCs?
did you only aplly to a handful of schools?
do you have any medical related extracurriculars?
(have you ever been convicted of a war crime?) 😛
