The interview process consists of two main stages. First, the online coding test evaluates problem-solving skills, logical thinking, and knowledge of data structures through coding questions. Candidates who qualify move to the technical interview, where they are assessed on programming concepts, projects, and core subjects like DBMS, OS, and OOPs.
