A typical software engineering interview process at Microsoft usually begins with an initial screening call, followed by one or more technical interviews that focus on data structures, algorithms, and system design. Candidates are also asked about past projects, problem-solving approaches, and collaboration experience. In many cases, the final stage is an onsite or virtual loop of several back-to-back interviews with different team members, each evaluating a different skill. This process helps the team assess both technical ability and overall fit for the role.
