Quora is the largest knowledge Q&A platform — 400M+ monthly visitors. Founded by ex-Facebook engineers; engineering culture is famously rigorous. The interview emphasizes recommendation systems, content quality, and the unique ML challenges of matching questions to answerers.
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 a question-answerer matching system
- Design content ranking with quality and engagement signals
- Design Quora’s Poe (LLM platform) bot ecosystem
- Coding: medium-hard DSA, often with graph or ML framing
- Behavioral: customer focus, ownership, working at scale
Levels and comp (2026)
- SE II: $160K–$200K total
- Senior SE: $230K–$310K
- Staff: $330K–$440K
- Principal: $460K–$620K
Prep priorities
- Be fluent in Python or C++ (the bulk of the codebase)
- Understand recommendation systems and ML for ranking
- Brush up on Poe / LLM API patterns
Frequently Asked Questions
Is Quora remote-friendly?
Distributed-first since 2020. ~400 employees globally.
How does Quora compare to Reddit or Stack Overflow?
Quora wins on broad-knowledge Q&A. Reddit on community discussion. Stack Overflow on technical Q&A. Quora is the smallest of the three by traffic but highest engagement per user.
What is the engineering bar?
High. Adam D’Angelo (founder, ex-Facebook CTO) set rigorous engineering culture. Strong ML focus given Poe.
