Modern React placements need more than “knows React.” Server Components, Suspense data flow, hydration tradeoffs, design-system discipline, build performance — the surface is wider than it was. sourceBOLD’s 4-gate gauntlet calibrates the technical screen against the actual React stack your team ships in: Next.js, RSC, Suspense + Streaming, design systems, tooling.
60-minute structured exercise calibrated against modern React patterns — hooks, Suspense boundaries, component composition, state management beyond useState. Two reviewers, blind to candidate identity, must agree to pass. Reviewers are Staff+ React engineers who currently ship production React.
Architecture round. We ask the candidate to walk through partitioning a real-world product surface — when to render server, when to render client, how data flows, what caches where. Same questions every time so the calibration is real, not vibes-based.
Two-hour real-codebase session. The candidate ships a small feature against a Next.js benchmark repo. We watch how they handle a stack trace, how they reach for the docs, how they communicate while debugging. Stack-specific judgment is what G4 catches that résumés don’t.
Full funnel walkthrough at /guides/4-gate-vetting — including G1 (communication assessment), the blind double- review pattern at G2, and why we publish the 4.2% acceptance rate rather than treating it as proprietary.
The contracting layer sits underneath all of this. From your team’s day-to-day, the developer is a senior React contractor on Slack. The cross-border tax shape, the bi-weekly invoice cycle, the Wise dispatch in the developer’s local currency — those are sourceBOLD’s operational concerns, not your team’s.
A succinct scoping call. Pre-vetted candidates. First standup in a few short weeks.
