HIRE FRONTEND ENGINEERS

Find Frontend Engineers Who Build Interfaces Users Love

Evaluate UI architecture thinking, performance optimization instincts, and design collaboration skills with structured assessments built for frontend hiring.

The Hiring Challenge

Frontend engineers shape every user interaction with your product. A great frontend engineer builds interfaces that are fast, accessible, and delightful. A poor one creates fragile UIs that break across browsers and frustrate users.

The problem: frontend skills span a vast spectrum. A candidate can build pixel-perfect components but struggle with state management at scale. They can write clean CSS but fail to consider accessibility or performance.

Common Hiring Mistakes

Testing CSS skills, not architecture

Centering a div doesn't tell you if they can design a scalable component system.

Ignoring performance instincts

Anyone can make it work. The question is whether it works fast.

Skipping design collaboration

Frontend engineers are the bridge between design and engineering. Communication matters.

Framework tunnel vision

React knowledge expires. Problem-solving ability compounds.

Sample Questions

Sample Assessment Questions

1
technical

You need to build a complex multi-step form with validation, conditional fields, and auto-save. Walk me through your architecture decisions.

What this reveals: Component design thinking, state management approach, awareness of edge cases (network failures, browser back button).

2
technical

A page loads in 8 seconds on mobile. Walk me through how you would diagnose and fix the performance issues.

What this reveals: Performance debugging methodology, awareness of Core Web Vitals, understanding of network/rendering pipeline.

3
technical

When do you decide a component should be reusable vs. purpose-built? Give me an example of each decision.

What this reveals: Architectural judgment, awareness of premature abstraction, pragmatic thinking.

4
behavioral

Tell me about a time you disagreed with a designer about implementation. How did you handle it?

What this reveals: Collaboration style, ability to advocate for technical constraints while respecting design intent.

5
behavioral

Describe a situation where requirements were ambiguous. How did you move forward?

What this reveals: Comfort with uncertainty, proactive communication, product thinking.

Evaluation Criteria

What separates strong candidates from weak ones across each competency.

UI Architecture

Great: Thinks in components, considers reusability vs. simplicity, understands rendering
Red flags: Monolithic components, no thought for state management, prop drilling everywhere

Performance

Great: Measures first, optimizes targeted areas, understands browser rendering pipeline
Red flags: Premature optimization or no optimization awareness at all

Accessibility

Great: Semantic HTML by default, keyboard navigation, screen reader testing
Red flags: Div soup, no ARIA awareness, dismissive of accessibility

Collaboration

Great: Bridges design and engineering, communicates trade-offs clearly
Red flags: Implements blindly or pushes back without alternatives

Code Quality

Great: Clean component APIs, meaningful tests, clear documentation
Red flags: Spaghetti code, no testing, unclear component boundaries

Frequently Asked Questions

How long does the frontend assessment take candidates?

35-45 minutes. Mix of video responses (architecture discussions, debugging scenarios) and written responses.

Does it test React/Vue/Angular specifically?

The default assessment focuses on framework-agnostic frontend concepts. You can customize to include framework-specific questions.

How is this different from a take-home coding test?

Take-homes test execution. LayersRank evaluates judgment, communication, and problem-solving approach — the things that predict job performance.

Can we see the questions before inviting candidates?

Yes. Full preview available after signup.
