+ A browser-based VS Code session with Claude Code available + throughout. You'll explore a small TypeScript/Node.js + codebase, add a focused feature, then implement a bigger one + from a deliberately concise spec. Before the technical + interview, Front-End and Full-Stack Engineer candidates go + through this additional step. +

+ Preparation +

+

+ Check out{" "} + + solidgate.com + {" "} + 💚 and get to know what we build. You don't need domain + knowledge going in — what matters is how you think, + communicate, and use AI tools like Claude. +

+
+
+

+ 1. 👋 Intro (5 min) +

+

+ Quick introductions, then a chance to ask any questions + upfront — about the role, the team, or how we work. +

+
+
+

+ 2. 🔍 Warm-Up — Explore the Environment (5 min) +

+

+ A browser-based VS Code environment, pre-configured + with Node.js, TypeScript, and Claude Code CLI. Read the + spec, run the tests, ask clarifying questions. +

+
+
+

+ 3. 🔧 Task 1 — Small Feature (15 min) +

+

+ A small, well-scoped feature on a pre-built TypeScript/ + Node.js app. Get oriented, make a focused change, verify + it works in the running app — not just that the code + looks right. +

+
+
+

+ 4. ✨ Task 2 — Feature Implementation (20 min) +

+

+ A bigger feature from a spec that's intentionally + concise. Treat it like a real ticket — ask clarifying + questions, read the code you're building on, consider + edge cases, verify your work. +

+
+
+

+ 5. ✅ Wrap-Up & Next Steps (5 min) +

+

+ A short debrief and what's next. Time to ask us + anything — about the role, the team, or the engineering + culture at Solidgate. +

+
+
+

+ What we're looking for +

+

+ Not whether you finish everything — how you approach + problems and collaborate with AI: +

+
    +
  • + Requirements Discovery — explore + before touching code; ask about what's left open + rather than assuming +
    • +
  • + AI Direction — give Claude specific, + bounded tasks; skip it when reading the code yourself + is faster +
    • +
  • + Verification & Debugging — read + AI-generated code before applying it; dig for root + cause, don't just patch symptoms +
    • +
  • + Judgment & Trade-offs — make + reasonable calls on scope and design, and say why +
    • +
  • + Communication — think out loud, + treat the interviewer as a pairing partner +
