Applied online on August 2014. Contacted by a recruiter on early September 2014, telling me there were two technical phone screens. I chose early October to do the interviews since I required extra time to prepare for my PhD proposal defense at the end of September. The first interview went relatively smoothly. The interviewer asked basic Python questions like what list comprehension is; what the time complexity of a very algorithm. Then he asked me to write some simple modules. I think anyone who are familiar with computer science could do it in minutes. The second interviewer did not call me in time so we rescheduled for another day in the same week. The interviewer asked me a trial algorithm question in the first round; then he extend it to a general case which required candidate must have a deep understanding of recursion. I did not make it within the time limit. Overall, it's a great experience.

One or two rounds of virtual interviewing including behavioral, research discussion, and technical interview. Then was flown out to one of their campuses for two in-person interviews including a technical interview and a research discussion. I was rejected after this phase but the next steps would have included meetings with team leaders for team placement.
