I realize the limits imposed in the form of the character limit, but it seems your entire essay focuses around "Why Waterloo" and not the initial "Your goals and Interests".
It may be tough at this point, but try to add at least a sentence or two initially, that tackle this prompt.
Winston, there is nothing impressive about the reasons you chose to apply to Waterloo. The explanation you gave can apply to any university in the United States. Your explanation does not merit any consideration because you do not show a clear familiarity with the program you have chosen to enroll in and why. You are not clearly explaining any reasons that would convince the reviewer that you know what you are getting into by applying to the university. There is no academic consideration, no academic goals that Waterloo can fulfill, and no professional ambition to prove that claim you made about Waterloo helping you to be employed by big name companies. Therefore, this essay is not one that you can use for this application. Try to write a new essay. One that uses specifics and highlights your familiarity with the outcome of your course choice, should you be admitted to and complete your studies at the university.
