Overall good experience, interviewers were nice and always right on time. The questions asked were medium LCs, not too hard, but you need to be ready to write some code and do it optimally. The CR round was a joke. Don't choose C++ as the code they will use is just awful, possibly a port from some Java code without taking any C++ idioms into account (e.g., passing everything by copy). You can flag them, but they seem to not care. You need to find bugs; that's all they are after. Very weird conception of code review, IMHO. Design architecture will be website-oriented, so make sure you know how to build a scalable website.
