i’m in the same boat but a med applicant. if you watch the video they linked what to expect for interview they break down the interview quite nicely. if the video is correct the interview doesn’t seem so daunting. i would use the prep you’ve done for your dent interviews and alter it to fit a pharmacy degree. at the end of the day you need the same communication, teamwork, empathy skills you need for a career in medicine/dentistry so i assume it would be similar things they are looking for at interview ? i haven’t sat the interview yet ofcourse but this is just my thoughts.
also did you manage to book a slot for your interview? when i clicked the link there was no slots left but i have been advised they release slots periodically and not to worry.
