I took a 1-hour online coding exam that had some multiple choice (mostly Big O questions) and a written response to a programming problem which many people on here have referred to as the Six Degrees of Separation question. After completing this I was asked to schedule a phone interview with an engineer. This consisted of him asking me what I knew about the company (um...) and what about that made me actually want to work there (uh...). Then he asked me more about my answer to the Six Degrees question. This guy was definitely an engineer and did not seem to be trained in how to interview a prospective applicant (a low talker, oy), but in fairness my interviewee skills left a lot to be desired this day. I was asked back for a second interview. This time, the interviewer was much better, a senior engineer that had been with the company for 5 years. He asked me about some of the projects I had done and the technologies I had used. He then asked me a question concerning keeping track of unique users during a given time period. What's the most efficient way, etc.? I was not asked back for an in-person interview after that.
