My resume was forwarded to this group through a friend. The recruiter got in touch to schedule a phone screen. They scheduled an additional one. First one focused on a string manipulation question and basic computer science, and OO concepts (stuff like threading basics, polymorphism). Also asked about work experience. Second one focused a lot more on my understanding of memory allocation - had to point out challenges/errors on a given custom memory allocator. And another question was an array-of-integers-related question. Was called onsite a week later. Had 5 rounds of interviews. Questions based on a mix of understanding of Computer science concepts—such as multi-threading, client-server behavior, http basics, scalability etc—and algorithms/coding as well as testing ability. Some of the coding related questions: reversal of sentence, sorting an array based on its modulo 'k' value, a 2-D array sorting related question. I got the offer a week later and accepted it.
