Microsoft coding interview — the patterns you should actually drill.

TL;DR

Microsoft's loop varies heavily by team (Azure, Windows, Office, LinkedIn), but most have 4 rounds: two coding, one system design or architecture, and one behavioral/manager screen. Senior+ loops add a deep-dive round.

Top 5 patterns at Microsoft

These patterns show up most often in publicly-reported Microsoft loops. Master the first three before you move on.

  1. #1
    Graph BFS / DFS

    Breadth-first for shortest unweighted paths; depth-first for exhaustive traversal.

  2. #2
    Dynamic Programming

    Break an overlapping-subproblem problem into a recurrence and cache results.

  3. #3
    Two Pointers

    Two cursors moving independently over a sorted or monotone structure.

  4. #4
    Backtracking

    DFS through a decision tree with pruning and state restoration.

  5. #5
    Union-Find (DSU)

    A disjoint-set data structure supporting near-constant merge and find.

System design

Microsoft system design emphasizes reliability and operational maturity — expect questions about SLA, deployment, and rollback. Azure-org loops skew toward cloud primitives.

Behavioral

Growth mindset is a stated rubric dimension. Stories that show 'I was wrong, here's what I learned' land better than flawless-hero narratives.

Microsoft quirk

Microsoft interviewers often ask for code to run in their head rather than on a compiler — dry-run discipline scores disproportionately.

Frequently asked questions

What patterns does Microsoft ask in coding interviews?
Most-reported patterns in Microsoft loops: Graph BFS / DFS, Dynamic Programming, Two Pointers, Backtracking, Union-Find (DSU). These 5 patterns cover the majority of the coding rounds.
How long is a Microsoft interview loop?
Microsoft's loop varies heavily by team (Azure, Windows, Office, LinkedIn), but most have 4 rounds: two coding, one system design or architecture, and one behavioral/manager screen. Senior+ loops add a deep-dive round.
What is unique about Microsoft's interview?
Microsoft interviewers often ask for code to run in their head rather than on a compiler — dry-run discipline scores disproportionately.
What does system design at Microsoft look like?
Microsoft system design emphasizes reliability and operational maturity — expect questions about SLA, deployment, and rollback. Azure-org loops skew toward cloud primitives.
How should I prepare behaviorally for Microsoft?
Growth mindset is a stated rubric dimension. Stories that show 'I was wrong, here's what I learned' land better than flawless-hero narratives.
How many weeks of prep do I need for a Microsoft onsite?
Most candidates benefit from 8–12 weeks of structured prep: 4 weeks on pattern fluency, 4 weeks on timed practice, and 2–4 weeks on mock interviews and Microsoft-specific topics.
