Microsoft Interview Roadmap
5 rounds · Coding #1, Coding #2, Coding #3, System Design, As Appropriate (AA). Prep strategy, system design patterns, and the exact focus areas Microsoft tests at each stage.
Interview Process
| # | Round | Duration | Focus Areas |
|---|---|---|---|
| 1 | Coding #1 | 60 min | DSA — arrays, strings, linked lists, graphs; expect 1–2 problems per round |
| 2 | Coding #2 | 60 min | DSA — second set; OOP design questions common for some roles |
| 3 | Coding #3 | 60 min | DSA — third set; behavioral questions integrated throughout all coding rounds |
| 4 | System Design | 60 min | Open-ended architecture — Azure-adjacent design common; scale and trade-offs expected |
| 5 | As Appropriate (AA) | 60 min | Final calibration with a senior leader — only triggered if prior rounds are strong; rare |

Key Concepts to Master
A distributed hashing scheme that minimizes key remapping when nodes are added or removed.
Asynchronous communication buffer between services. Decouples producers from consumers and provides durability during traffic spikes.
The problem of getting distributed nodes to agree on a single value despite network failures and partial outages. The theoretical foundation behind etcd, ZooKeeper, and Kafka leader election.
A shared cache layer across multiple nodes used to absorb read traffic from the primary database and reduce latency on hot data paths. The difference between a 2ms and a 200ms read at scale.
Object storage for unstructured binary data: images, videos, documents, ML model weights. Designed for durability and throughput at scale, not low-latency random access.
