I applied online and was contacted by an HR person. They arranged two phone interviews. Unfortunately, one of the HR persons I was working with quit her job. As a result, I was forgotten about for a few weeks. I contacted her manager, who went back to recollect the feedback. Unfortunately, the feedback was negative. :(

The question was very hard to think about in the span of 35 minutes, especially because the interviewer had a heavy accent and was chewing on something in the background.

The second interviewer asked how to create a silhouette given a list of buildings.

Details: You are given a list of buildings represented with <starting point, end point, height>. Return an ordered list of points that represents the silhouette. The points are represented with <X Coordinate, Y Coordinate>. Do not assume the buildings are sorted in any way.
