Took about two month, one phone interview and five rounds onsite interview. The recruiter and the interviewers are all really nice. Their new office in 32nd street in Manhattan is awesome because of their 130 million fund in 2015 March. Due to NDA, I cannot say out the specific questions. But I have to say the bar is similar to Google, Facebook and other tech giants. Questions are originally created themselves, and can test a large range of your skill and knowledge in terms of algorithms, system design and open-end problem thinking. For the culture and atmosphere, it's one of the best among dozens of companies I've been interviewed in, like Goldman, Morgan Stanley and Amazon.
