I know how you feel, I've been in the same boat for many years. This is my 5th time applying, 3rd time interviewing. I have had close to 10 interviews over the last 5 cycles and was rejected post interview at every single one of them. I also had below average interview score at UBC the last 2 times I was rejected. I only have the old MCAT score and I felt like giving up after this year, but it somehow worked out. Please don't give up because you never know what could happen next year. What is one more year in a 40 year long career for something you love to do for the rest of your life.
