Hi everyone,
I'm a current student at UCBSO, and last year they interviewed 105 people and 73 of those interviewees were offered a spot in the program. The size of the class of 2015 is 66 students. I can tell you first hand that once you are offered an interview, numbers no longer matter. Your written application (including your GPA/OAT) are what get you an interview, but after that, everybody is on an equal playing field. What counts is how well you perform during the interview. Basically, the interview is not completely open, but the interviewers have your essays in front of them, and the panel (one staff member + one 3rd or 4th year student) ask you questions about what you wrote in the essays, about your character, and about optometry. It's meant to feel conversational. There is also a team activity, basically assessing whether or not you can work well in groups. There is also an essay to make sure you can form an opinion and write coherent paragraphs (because the reality is that you could have had help writing your personal statement and supplementary essays).
I would say that if you're personable and passionate about optometry/going to UC Berkeley's program, then you have a great shot at being accepted. It's important to smile and be yourself! Also, do dress professionally (suits) and wear comfortable shoes. Bring an appetite because you will be treated to a yummy catered hot lunch! 🙂 Have fun and good luck! I hope to see you all around Minor Hall next year!
