Meta interview structure — end to end
The Meta interview process moves fast. After applying, you'll typically hear from a recruiter within 1–2 weeks. The full timeline is usually 4–6 weeks: 1. **Recruiter Screen** — 30 min non-technical call about your background and motivations. 2. **Technical Phone Screen** — 45 min with one engineer. One coding problem. Must solve it completely and optimally to advance. The problem is almost always a Graph or DP medium-hard. 3. **On-site (Virtual) Loop** — Typically 5 rounds in one day: - Coding Round 1 + 2: Two problems each, 45 minutes. Mix of Medium and Hard. - System Design: One design question, scaled to Meta size. - Behavioral/Values: Structured questions around Meta's core values. - (For senior roles): An additional Leadership/Execution round. 4. **Debrief + Offer** — Meta moves quickly post-loop; verbal feedback within 2–5 days. Key difference from Amazon: **Meta does not do LPs**. Behavioral questions at Meta are values-based and less structured.
DSA deep dive — what Meta actually asks
Meta's coding questions skew harder than Amazon's and are more algorithm-focused than Google's. The most common patterns in Meta interviews: **Graphs (highest frequency):** - Clone Graph, Number of Islands, Word Ladder, Accounts Merge, Minimum Spanning Tree, Cheapest Flights Within K Stops, Critical Connections in a Network **Dynamic Programming:** - Longest Increasing Subsequence, Edit Distance, Decode Ways, Interleaving String, Burst Balloons, Regular Expression Matching **Trees:** - Binary Tree Vertical Order Traversal, Serialize/Deserialize, Diameter, LCA, Path Sum III, Boundary Traversal **Arrays/Strings:** - Minimum Window Substring, Trapping Rain Water, Next Permutation, Largest Rectangle in Histogram, Valid Parentheses variants **Backtracking:** - Word Search II (with Trie), N-Queens, Permutations II, Generate Parentheses Practice tip: Meta expects you to produce **clean, bug-free code** in your language of choice. Python is fine but write it like a professional: no one-liners that obscure logic, proper variable names, and handle edge cases.
System design at Meta scale
Meta system design is distinguished by one factor: **extreme scale**. 3 billion users, petabytes of data, sub-200ms response times globally. This changes the design decisions you make. **The Meta design framework:** **Step 1 — Define the problem clearly (5 min)** Meta interviewers want you to drive. Ask: "What are the core features?" "What is the target scale?" "What are the consistency requirements?" Then state your assumptions explicitly. **Step 2 — Estimate scale (3 min)** - Facebook-scale: 3B MAU, 1B DAU - News Feed writes: ~500M posts/day = ~6K writes/second - News Feed reads: 10x writes = ~60K reads/second - Storage: Photos average 3MB × 350M photos/day = 1PB/day just for photos **Step 3 — Core design (20 min)** Draw: client → API layer → core services → storage. Name real technologies (Cassandra for user timelines, TAO for social graph, Memcache for feeds, Scuba for analytics). Meta uses specialized databases — knowing these signals genuine interest. **Step 4 — Deep dives (15 min)** Common Meta deep dives: Fan-out architecture for News Feed (push vs pull model), CDN for media delivery, consistency model for chat messages (WhatsApp-style), and real-time delivery via long polling vs WebSocket. **Design to master first:** Facebook News Feed. It covers fanout (write vs read time), ranking (ML model inputs), caching (Memcache), storage (Cassandra + MySQL), and real-time delivery (push). This single design touches almost every distributed systems concept.
Meta core values — behavioral prep
Meta evaluates behavioral fit through its **core values** rather than structured principles like Amazon's LPs. The five values are: **Move Fast:** Meta was built on "move fast and break things" (now "move fast with stable infrastructure"). Prepare stories of shipping under tight deadlines, making quick but informed decisions, and iterating rapidly based on feedback. **Build for Openness:** Transparency, sharing information broadly, and building products that connect people. Stories of sharing knowledge, removing information silos, or building tools that democratized access internally. **Focus on Impact:** Everything Meta does is measured by impact. Your stories should always end with a quantified result — percentage improvements, user numbers, revenue impact, or time saved. "Impact" is the most common word in Meta feedback. **Be Bold:** Take risks, push boundaries, challenge the status quo. Stories where you proposed a non-obvious solution, pushed back on a spec that wasn't ambitious enough, or took a calculated risk that paid off. **Be Open:** Give and receive feedback. A story where you received critical feedback and used it to improve, or where you delivered difficult feedback to a colleague in a constructive way. **STAR format at Meta:** Situation (brief), Task (what was your responsibility), Action (85% of the answer — what YOU specifically did), Result (quantified). Meta interviewers follow up aggressively — "What specifically did you do?" "Why that approach?" — so your actions must be personal and specific, not "the team did X."
Meta compensation in 2026
Meta pays at or above FAANG median. Unlike Amazon, Meta has no RSU vesting cliff — RSUs vest quarterly from Day 1, typically over 4 years. **Typical 2026 US ranges (Bay Area/NYC):** - E3 (SWE I, 0–2 YoE): Base $175K–$210K, TC $250K–$320K - E4 (SWE II, 3–5 YoE): Base $210K–$250K, TC $320K–$430K - E5 (Senior SWE, 6–9 YoE): Base $250K–$290K, TC $450K–$650K - E6 (Staff SWE, 10+ YoE): Base $280K–$350K (capped), TC $700K–$1.2M+ Meta's RSU grants refresh annually based on performance ratings. An E5 with an "Exceeds Expectations" rating typically receives a 30–50% RSU refresh, significantly boosting Year 3+ TC. Negotiate your initial equity grant hard — it sets the refresh baseline.
