Postman is the leading API development platform — used by 30M+ developers for testing, documentation, and collaboration. Series D, $5.6B+ valuation. The interview emphasizes large-scale developer-tooling engineering, real-time collaboration on API specs, and the operational realities of a freemium SaaS at scale.
Process
Recruiter screen → 60-minute coding phone (TypeScript or language of choice) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–5 weeks.
What they actually ask
- Design a real-time collaborative API workspace
- Design a request-execution engine that runs millions of saved requests/day
- Design a mock server platform for API stubbing
- Coding: medium DSA, often with API or workflow framing
- Behavioral: developer empathy, ownership, working with diverse customer base
Levels and comp (2026)

Frequently Asked Questions
Is Postman remote-friendly?
Distributed-first since founding. Hubs in San Francisco, Bangalore, NYC. Most engineering roles remote across US/India.
How does Postman compare to Insomnia or Bruno?
Postman is the largest by mile (30M+ users). Insomnia is owned by Kong; smaller and lean. Bruno is a newer open-source competitor that resonates with Postman power users frustrated with the cloud-only direction. Comp at Postman is competitive for senior+ developer-tooling work.
What is the engineering culture?
Mature, customer-driven, calmer pace. Strong written-first culture with India-US distributed time zones requiring async discipline.
