Frontend interview prep, head-to-head
Generic SWE copilots default to data-structures hints. Frontend rounds need component-tree reasoning, layout-thrash analysis, and design-system scope calls — three categories most copilots cannot articulate.
Calibrated for the modern frontend loop
Component-architecture rounds
When the interviewer says "build me a typeahead", the copilot does not jump to code. It surfaces the right clarifying questions — debounce vs throttle, controlled vs uncontrolled, accessibility expectations, error states — then suggests a component-tree skeleton with the right separation between view, logic, and side effects.
React internals depth
Hooks rules, reconciliation, fiber, Suspense, concurrent rendering, useMemo vs useCallback vs useTransition — when the interviewer asks why your code re-rendered, the copilot surfaces the actual mechanism (parent rerender, context churn, ref-equality trap) instead of guessing.
CSS at scale, not just CSS basics
Specificity wars, cascade pitfalls, layout vs paint vs composite, container queries, logical properties — Interview Lift is one of the few copilots that articulates *why* a CSS change triggers a layout thrash, not just *that* it does.
Performance rounds — Core Web Vitals fluency
When the round is "we have a slow page, debug it", the copilot scaffolds the diagnostic: LCP candidate identification, INP profiling, CLS root-cause, render-blocking analysis, hydration cost. You sound like the engineer who has shipped a production perf fix before, not memorised a Lighthouse report.
Frontend system design
Design a design system. Architect a micro-frontend split. Design an offline-first PWA. Frontend system design is a real round at senior FE loops — and most copilots have no scaffolds for it. Interview Lift has six, one per common prompt.
Accessibility + i18n callouts on every round
WCAG conformance, ARIA live regions, screen-reader announcement timing, RTL layout pitfalls. The copilot flags accessibility decisions early in your answer so a senior FE interviewer recognises you have shipped accessible UI before, not just read about it.
