Got a call from one of the engineers, who said they were interested in my resume. Had one phone screen where I was asked general object-oriented questions, and an onsite interview that lasted about two hours. This involved coding on a whiteboard, explaining the roles of different networking hardware, and figuring out what a snippet of code was doing by looking at it. Got called about a month later for the offer.

Name the different parts of a network system and explain their role.
