There are no turkeys in admissions. They are competent professionals who are doing their best to fill the class with interesting students. Someone were admitted with great stats, some with interesting experience or background and other reasons (holistic)
Your stats is competitive and I am a bit surprised of your rejection and not putting you on wait list.
However , I have no idea how you compare to others still waiting.
I met with the admissions staff on many occasions while I was there and I can attest that they are very dedicated,helpful and caring. .
Some of the OZ admissions staff is also a member or reader of this forum.
