The Full Stack Development skill check.Five topics, one question each.
Question 1 is below exactly as the check asks it. The answer, and why it is right, come with your result.
Full stack engineering remains one of the most versatile and in-demand roles in software. But the breadth of skills required — from HTTP protocols to database design to frontend frameworks — makes it hard to know where your gaps are.
This diagnostic covers five areas that full stack interviews consistently test: HTTP status codes and API design, SQL injection prevention, secure authentication patterns, database indexing, and React fundamentals.
Three minutes, five questions, and you'll know exactly which areas need work before your next interview or project.
- HTTP & APIs
Every full stack role requires solid understanding of HTTP semantics.
- Database security
SQL injection is still one of the most exploited vulnerabilities: interviewers expect you to prevent it.
- Auth
Secure token handling is non-negotiable in production applications.
- Databases
Understanding indexes is what separates fast applications from slow ones.
- React
Component key management affects rendering performance and correctness.
Which HTTP status code means 'created successfully'?
- A404
- B201
- C200
- D400
“Learn AI” means three things.This check tests one of them.
It is not an AI quiz. It tests the web engineering LLM features ship inside: APIs, auth, databases, security and React.
- 01
Machine learning foundations
How models learn from data: the statistics, training and evaluation underneath them.
For you ifyou want to train and judge models, as an ML engineer or data scientist.
Take the Machine Learning check - 02This check
Applied LLM engineering
Building software on models like Claude and GPT: prompts, retrieval, agents, evals and shipping.
For you ifyou write code and want to build AI features, not train models from scratch.
- 03
AI for your job
Using AI tools well in the work you already do: briefing them, checking what comes back, keeping data safe.
For you ifyou do not plan to code and want AI to make the work you do faster and better.

Programmes that build on this check.Your result shows where to start.
Each one teaches Full Stack Development by building, and ends in deployed work graded against a rubric you can read.
Before you start.Three quick answers.
What does this full stack check cover?
HTTP and API conventions, SQL injection prevention, JWT authentication best practices, database indexing, and React component patterns.
Which frameworks does it test?
The questions are framework-agnostic where possible, with one React-specific question. The concepts apply across frameworks.
Can I retake it?
Yes — you can retake it any time. For a deeper assessment, sign up for the free full assessment.
