I handed in my resume via my school's co-op website.

I ended up getting an interview, which had two rounds.

The interviewer was really friendly, and I felt comfortable talking with him. He asked me about my side projects and talked about the type of work he did and the work previous interns did.

Unfortunately, I didn't get to the second round.

The interview problems were fairly straightforward. One was given two nodes in a binary tree; find the closest ancestor. The other problem was given a 2D array of people who follow one another; determine who's an influencer (followed by everyone, follows no one). For example, if A[i][j] is true, then person i follows person j.
