I had a rather lengthy discussion during the Skype interview about how garbage collectors were implemented in various languages. I don't know if I would say it was a question perse, but it was difficult giving adequate explanations of each, discussing not only the implementation but also the pros and cons. I also had a question about finding the largest prime divisor of a number, which I thought was difficult because the question itself was so easy, so it was kinda difficult to find good ways to optimize.

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