I recently completed four rounds of interviews with Microsoft. The process primarily focused on core technical concepts, including Data Structures and Algorithms (DSA), tree-based problems, Low-Level Design (LLD), and High-Level Design (HLD). Each round tested not only my problem-solving skills but also my system design capabilities and overall software engineering approach. It was a well-rounded and challenging interview experience that gave me good insight into what Microsoft values in its engineering candidates.
