The overall interview process was long. From recruiter point of contact to the initial phone screen then two phone interviews the entire process took five weeks. It also took a while to prepare since the interviews were really testing out your analytical, problem solving ability on the fly. So remember have enough sleep before the day of interview, don't be like me staying up late to prepare for it, really crams your brain thinking speed. Another tip I would give is to practice listening to foreign accents, it happened to my second interview, with the interviewer speaking heavy accent over unstable Google Hangouts internet phone call I had to ask for clarification on all of his questions and I think this really harmed my ability in thinking and responding clearly. After a week of the second phone interview I was contacted by recruiter saying they would not be moving forward with me to the next round but encourage me to reapply. I asked for specific details but was told its classified information.
