Candidates answer multiple-choice questions in JavaScript, SQL, REST API, CSS, Git; workplace situations in Problem Solving online. They do not complete your day-to-day work inside your own systems. Add a short work sample based on reviewing a code change against its acceptance criteria to explore application alongside the test results.

Why is JavaScript included?

Checks JavaScript knowledge for building interactive application code. Discuss functions, objects and the behaviour of browser interactions in a small code example. Review whether this area reflects the responsibilities of your vacancy before retaining it.

How long does this Full Stack Developer assessment take?

The recommended selection contains 6 tests and allows 60 minutes across its timed tests. Adding or removing tests, or adjusting time allowances, can change the total.
