Evidence-based technical screens for Senior Frontend Engineers
Frontend CVs are full of framework names. CheckAnyCandidate extracts the actual work claimed and generates probes that test reasoning: performance trade-offs, rendering decisions, accessibility under constraint, and how they handled the things that broke. The runtime records what each answer established and what is still uncertain, so your decision rests on evidence, not polish.
You run the interview and make the call. We lay out the evidence, never a score or a verdict, and never watch the candidate.
Example probe for a Senior Frontend Engineer
Generated from a real CV claim. Every probe targets the evidence one claim needs, with a follow-up perturbation to reach it.
“Reduced initial bundle size by 35% through code splitting and lazy loading.”
Tell me about a component or route that was hard to split. What made it difficult and how did you decide where to draw the boundaries?
Now assume a product manager wants to add a feature that requires loading a 200KB third-party library on the landing page. How do you approach that conversation and what alternatives do you explore?
Dynamic import trade-offs, waterfall risk, perceived vs actual performance, negotiating with stakeholders, bundle analysis, prefetch strategy.
Only naming React.lazy and Suspense, no discussion of trade-offs or real constraints encountered.
What a good Senior Frontend Engineer screen tests
CheckAnyCandidate generates probes across all of these areas from the candidate's own CV.
- +Performance diagnosis and trade-offs
- +Rendering strategies (SSR, CSR, hydration)
- +Accessibility under real constraints
- +State management decisions
- +Design system ownership
What Senior Frontend Engineer CVs typically claim

- “Led migration from class components to hooks across a 200k-line codebase”
- “Reduced bundle size by 35% through code splitting and lazy loading”
- “Owned the design system used by five product teams”
