Worst Yet: University of Waterloo.
The Quest App. Lets me upload my transcripts, CV. I could never see what was uploaded later, and had to mail them to upload a missing transcript, after backtracking and soul searching what file I clicked.
UMass: As someone had mentioned, Some stuff disappeared from my app after save n log off and the there is no way of seeing what I submitted later.
Worst Part: I submit my application, go to pick my credit card from living room, the session times out and i had to re-write my whole app, cos i knew that grad admissions office is great.
Alberta:
They have provided statutory warning in the site for Computer Science department applications.
"EXTREMELY IMPORTANT that you "log out" in order to complete your session and to write your file to the database"
Goddamnit its, CS deparment.
My key learnings:
Never submit application before review. Never take a pee break while submitting an online application.
