MS Canada interview questions

I had a call with the manager. He asked me to explain something difficult I had learned recently. I explained integrals and some other calculus concepts because I was a first year engineering student. They were very nice, and asked relevant follow-up questions to see how I think.

Two interviews. On time. Informative. Positive experience. Organized. Thoughtful questions. Took notes Allowed space to think Two people at each interview. They typed notes. Asked if I had questions. Nothing alarming
