Three hour HackerRank challenge after submitting resume followed by a phone screen to go over resume and basic questions any interviewer would ask you. Got invited for an in person interview. I was told by the person giving me the phone interview that it would involve pair programming exercises to see how you worked and how well you would fit in with the company. They gave me three general topics that were covered that ended up being inaccurate. Interview day included a presentation about the company, three hour-long HackRanks, and getting lunch with some employees. I liked the company and most people I interacted with but two of the "Pair Programming" exercises had the least engaging interviewers I have ever encountered. They basically said nothing and sat there disinterested for the entire hour. Received a rejection email a couple days later.
