Meta software engineering hiring runs on an interview process, not a single written exam — an online assessment, then a loop of onsite (or virtual onsite) rounds mixing coding, product-architecture, system design, and behavioral interviews. The exact rounds vary by level (E4/SDE-2 vs E5/E6) and role family, but the outline below is the pattern that shows up most consistently across recent (2025) candidate reports.
Typical Meta interview process
| Stage | What it tests | Typical length |
|---|---|---|
| Online Assessment | Multi-stage coding assessment (often 4–5 stages), sometimes with a behavioral component | 90–150 min |
| Onsite / Loop coding rounds (2–3) | DSA — arrays, graphs, trees, strings, hash tables, sometimes with AI-assistance tooling enabled | 35–45 min each |
| Product architecture / design round | Requirements, entity modeling and API design for a product like a food-delivery app or a booking system | 45 min |
| System design (E5/E6 onward) | Large-scale design — feed ranking, ad delivery, real-time leaderboards | 45 min |
| Behavioral | 7–10 STAR-format questions on ownership, conflict, ambiguity and cross-team alignment | 35–45 min |
Rounds routinely run under strict 35–40 minute time limits, and interviewers follow up quickly on behavioral answers — see the Behavioral & Culture-Fit Interview Questions section to prepare for these directly.
Process varies by level and role family. E4 loops lean more heavily on DSA and a product-architecture round; E5 and above loops regularly add a dedicated system design round, and leveling can shift mid-loop — candidates have reported strong performance still being downleveled at offer time.
Prepare each track on its own terms: DSA, System Design (HLD), and Behavioral & Culture-Fit.
