Microsoft·Software Engineer·Onsite - Behavioral / Leadership
Apr 2026
Microsoft software engineering interview focused almost entirely on behavioral rounds, with three main prompts covering ambiguity, technical disagreement, and a self-intro deep dive. No coding or system design on the slate, which surprised me a little.
- Tell me about a time you had to deliver something with very little information or guidance. How did you decide what to prioritize?
- During that same delivery, did you introduce a code freeze? Walk me through that decision.
- How did you maintain parity between systems or versions during a migration?
- Describe how you ran an A/B experiment or staged rollout, including how you controlled risk, defined success metrics, and handled rollback.
- Describe a significant disagreement you had with another engineer or stakeholder over a technical design. What was the disagreement, how did you work through it, and what shipped in the end?
- Give a brief intro of your background and walk through one or two projects, then be ready to answer detailed questions about the decisions you made.
“This one has a lot of surface area.” The rest of the author's notes on Software Engineer interview at Microsoft, Onsite - Behavioral / Leadership round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
