I had my applications in by October to most places, so a little later than I would have lliked but still well within the deadlines, but my application was considered incomplete as I was waiting until December for my final reference letter from a physical therapist to be written and my observation hours confirmed.
But luckily since then the interviews have been rolling in, even from places who supposedly already passed their deadline. And hopefully I'll be towards the top of UTC's waiting list and won't be waiting for too long.
