Sentry is the dominant open-source-friendly error monitoring and APM platform — used by Disney, Microsoft, GitHub, and tens of thousands of others. The interview blends data-pipeline design (think 100B+ events per month), backend engineering, and developer-tools sensibility. Sentry hires for craft.
Process
Recruiter screen → 60-minute coding pair (often Python or TypeScript, practical) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.
What they actually ask
- Design an error ingestion pipeline that handles 1M events/sec with bursty traffic
- Design a stack-trace symbolicator for native code (iOS, Android, C++)
- Design grouping logic — same error from different stack traces should cluster
- Coding: practical refactors, often involving event parsing or data transformation
- Behavioral: customer empathy (developers are the customer), open source contribution

Frequently Asked Questions
Is Sentry remote-friendly?
Distributed-first across US and EU. Hubs in San Francisco, Vienna, Toronto are optional.
What is the interview vibe?
Calm, conversational, and highly technical. Interviewers are typically engineers who shipped real systems; expect meaningful follow-up questions, not gotchas.
How does Sentry compare to Datadog or New Relic?
Sentry is developer-first and open-source friendly. Datadog is broader infra/APM. New Relic is older and more enterprise-flavored. Comp at Sentry lags Datadog by ~10–15% on senior+ levels.
