I applied online after talking to a recruiter at my university.

Within a few days, I received an email about setting up an initial phone interview.

The call was awkward and did not go well, as I forgot a lot of basic material.

Within a couple of days, I received an email stating I would not be moving forward.

Given a social network graph (nodes = people, edges = friendships between people) and a starting person, print the level of friendship for every other person with that person.

That is, print the minimum number of "hops" (edges) to get from the start person to every other person.
