Since the interviews are starting soon, here is what I personally found important
1) You need to have a plan for your MBA. Yes it can change, no one will deny that. But you cannot say I will see where I can fit in the program and then plan my post MBA goals... Generally the best is to have a 70% concreat plan and then 30% flexibility with relevant unknowns.
2) MBA program should be a must for career plan. If there are alternate ways to reach your post MBA goals then you plan is weak. And then fit in Canada and then Schulich. Why Schulich is probably the most important question.
3) Know your strengths and weakness. Your strengths should be relevant to your career plan. And your weekness should be something that can be easily covered during the MBA program.
4) Try to add as many different stories as you can. Don't repeat stories. Tell them about another time.
5) Have some out of the application interesting facts about you to share.
6) Do your Schulich research... Read why Schulich is famous... What is known for... Some of the most recent developments... Such as Digital Mainstreet
The basic aim is to make the interviewer feel that he/she can go out on a coffee chat with you.
Hope this helps.
