I'm a current student, and we have fantastic faculty and staff at WesternU. The interview I had there was very relaxed and felt just like talking to a buddy (I had Dr. Maeda). This was the opposite of my SCCO interview, which felt like the two interviewers were staring into my soul the whole time, and really grilling me with questions.
Again, it's all behavioral questions, so more like "when have you helped a friend in need?" than "describe your business model for your future optometric career."
