Mixpanel is the original product-analytics platform — funnels, retention, and behavioral cohorts at scale. Used by 8,000+ companies including Yelp, Uber, and Pinterest. The interview is data-pipeline-heavy, with strong emphasis on real-time event ingestion and ad-hoc query performance over billions of rows.
Process
Recruiter screen → 60-minute coding phone (DSA medium) → onsite virtual: 2 coding (one DSA, one practical), 1 system design (always analytics-flavored), 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.
What they actually ask
- Design a real-time funnel analysis engine over billions of events
- Design a cohort builder with arbitrary filter combinations
- Design event ingestion at 500K events/sec with bursty traffic
- Coding: graph/tree problems with data-engineering flavor
- Behavioral: customer focus, navigating ambiguity, working with growth/PM teams
