Amplitude is one of the leading product analytics platforms, used by 50,000+ companies to track user behavior. The interview is data-pipeline-heavy, with deep system design focus on event ingestion, real-time aggregation, and the brutal performance requirements of cohort/funnel/retention queries on billion-row datasets.
Process
Recruiter screen → 60-minute coding phone (DSA medium-hard) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.
What they actually ask
- Design an event ingestion pipeline handling 1M events/sec with deduplication
- Design a funnel analysis query engine over 100B events
- Design a real-time cohort builder with arbitrary filter combinations
- Coding: graph/tree problems, occasionally with data-engineering flavor
- Behavioral: customer focus, taking ownership, working through ambiguity
