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.

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.
