I first had a phone interview with Seth, and he asked me broad questions like "what has challenged you most?" and he asked me to describe some of the projects from my resume. Later that week, he asked me to come in for an in-person interview. I interviewed with Seth, and two of the lead software engineers. I was presented with questions including the following problems/questions (I'm paraphrasing): "What is your favorite data structure, and why?" "Convert a byte string of known length to a base64 string." Some very basic questions about traversing a binary search tree.
