HIRE FULL STACK DEVELOPERS

Find Full Stack Developers Who Ship Complete Features

Evaluate end-to-end thinking, cross-stack proficiency, and product orientation with structured assessments designed for full stack hiring.

The Hiring Challenge

Full stack developers own features from database to UI. A great full stack developer ships complete, working features independently. A poor one creates half-finished work that requires constant handoffs.

The problem: “full stack” means different things everywhere. Some candidates are strong backend engineers who can copy-paste React. Others are frontend specialists who can write Express routes. Identifying true full stack capability requires evaluating both depth and breadth.

Common Hiring Mistakes

Testing one side of the stack

A backend test + frontend test ≠ full stack evaluation. Integration thinking is the skill.

Ignoring product orientation

Full stack developers need to think about user outcomes, not just code.

Overweighting depth over breadth

Full stack is about effective problem-solving across the stack, not expertise in every layer.

Skipping autonomy assessment

The value of full stack is independence. If they need constant direction, the role doesn’t work.

Sample Questions

Sample Assessment Questions

1
technical

You need to build a feature that lets users upload a CSV, process it, and display results in a dashboard. Walk me through how you would sequence the work.

What this reveals: End-to-end thinking, task decomposition, awareness of both frontend and backend concerns.

2
technical

A user reports that data on the dashboard doesn’t match what they entered in the form. Walk me through how you debug this across the stack.

What this reveals: Cross-stack debugging methodology, understanding of data flow, systematic approach.

3
technical

When building a new feature, how do you decide what logic goes in the frontend vs. the backend?

What this reveals: Architectural judgment, understanding of security/performance implications, practical experience.

4
behavioral

Tell me about a time you had to learn a new technology quickly to deliver a feature. What was your approach?

What this reveals: Learning agility, pragmatism, ability to be effective without deep expertise.

5
behavioral

Describe a situation where product requirements were unclear. How did you decide what to build?

What this reveals: Product thinking, initiative, communication with stakeholders.

Frequently Asked Questions

How long does the full stack assessment take?

35-45 minutes. Covers both frontend and backend scenarios plus behavioral questions.

How do you evaluate breadth vs. depth?

We assess practical problem-solving across the stack, not framework expertise. The assessment tests integration thinking and end-to-end delivery capability.

What if our full stack role is backend-heavy?

You can adjust dimension weights. Our default balances both, but you can emphasize backend or frontend.

Can we see the questions before inviting candidates?

Yes. Full preview available after signup.
