Fewer rounds of technical interviews, but they are a bit difficult to clear. They mostly test your analytical and debugging skills. There will be a written test for technical roles, even if you have several years of experience.

Three technical rounds. First round is a written test. Second round is data structures, algorithms with two panels. Third round is more of deep C++ questions like threading, bitwise, and Linux. Last is a managerial round.

I had one telephonic screening. The interviewer asked very basic data structure questions, such as: * Inserting at the start of a linked list * The difference between `calloc` and `malloc` * Abstract virtual functions
