I applied through their website in early 2014 and I was contacted 3-4 months later. It caught me by surprise. The interviews consisted of 1 phone screen - which wasn't technical. I was then asked to come in for an onsite interview. The onsite consisted of 3 back-to-back interviews with engineers. I was given regular updates by the recruiter and I felt the people I met were quite straightforward and honest.

4 rounds in total 1 was with end director about past exp 1 was code given and review, mainly security and other issues 1 was system design, a particular part of big system in detail 1 was code review but make it modular, performance, API calls etc
