Good luck on the application process. UCSF does look at applicant's overall picture (way beyond GPA and scores). Thus, the essay, interview, situation responses, and extracurricular matter a lot. We use to joke around about the "human condition" essay questions. I think no one will ever be satisfied with their essay because no one really understand the human condition cus it can be anything! I agree with the advice to not list your resume and pick topics that are meaningful and tell a story that answers the prompt.
As for pharmacy prospect, there are lot of negativity about the satuation and such of too many pharmacy school and I completely understand. However, I always say, if there is 10 jobs and 11 people applying, you can be the one that doesn't get a job but if there are one job and 10 people applying, you can be the one who get it. Everything is based on the individual so just work hard and do what you love because that will show. I would advice you to specialize if you can. You say you want to work in hospital but that could be a outpatient dispensing, inpatient, ambulatory care or clinical. Some of these and probably by the time you graduate, residency might be desirable to really go far in pharmacy, be more competitive and hopefully find a niche in pharmacy you enjoy.
I am a pharmD who worked in a health plan and now in large pharmaceutical company in the field of Health Economics & Outcomes Research. Most people in pharmacy never even heard of this but that's what I mean. Open you eyes and explore everything you can do with a PharmD and not put your head in a sand and worry about the job market that you cannot change. First thing first, get into a good school you think will help you along this path.
