Sourcegraph Interview Guide (2026): Code Intelligence Engineering

Sourcegraph

sourcegraph.com ↗

Sourcegraph is the code-intelligence platform — universal code search across repositories, plus Cody (an AI coding assistant). Used by Uber, Lyft, Reddit, GE, and many others. The interview emphasizes code-graph engineering, large-scale indexing (Zoekt, SCIP), and the systems work behind LSP-like tooling at organization scale.

Process

Recruiter screen → 60-minute coding (DSA medium, language of choice) → onsite virtual: 2 coding, 1 system design, 1 craft deep-dive, 1 behavioral. Cycle: 3–4 weeks.

What they actually ask

  • Design a code-search index over millions of repositories
  • Design a precise code-graph using SCIP/LSIF for cross-repo navigation
  • Design RAG over a code corpus for an AI coding assistant
  • Coding: medium DSA, often with parsing, trie, or graph framing
  • Behavioral: developer empathy, ownership, written-first culture

Levels and comp (2026)

  • Engineer (E3): $175K–$230K total
  • Senior Engineer (E4): $230K–$310K
  • Staff (E5): $310K–$420K
  • Principal (E6): $420K–$580K

(Bands published openly on the Sourcegraph handbook.)

Prep priorities

  1. Be fluent in Go (most of the backend) and TypeScript (frontend, Cody)
  2. Understand code-indexing concepts (Zoekt n-gram search, SCIP/LSIF graphs, tree-sitter)
  3. Brush up on RAG patterns over code (chunking, embeddings, code-aware retrieval)

Frequently Asked Questions

Is Sourcegraph remote-friendly?

Fully distributed. No physical HQ. Engineers across the Americas, Europe, and APAC. Annual all-hands in person.

How does Sourcegraph compare to GitHub Copilot or Cursor?

Copilot is editor-embedded for individual devs. Cursor is an AI-first IDE. Sourcegraph (Cody + Code Search) emphasizes large-org code-graph context. Comp is competitive at senior+ with strong remote flexibility.

What is the engineering culture?

Async, written-first (everything in handbook/RFCs), high autonomy, ship-focused. Strong fit for engineers who prefer writing over meetings.
