Applied on their website in November. Was contacted via e-mail by recruiter from FAST in December. Had a quick 20-30min phone screening soon after where they asked some high-level OOP questions along with some behavioral questions, and after moving forward, was flown to headquarters in CO for in-person interview. The in-person interview consisted of an office tour, a 30min M.C. logic test w/ 2 written pseudocode problems, ~30 whiteboard logic problems with interview, then some behavioral questions. Some of the logic puzzles were tricky, but it seemed like they were primarily interested in your thought process rather than your ability to reach the correct answer (although that's probably important too). They were all extremely friendly and pleasant to interview with! After 3-4 weeks, they extended an offer.
