TRY AN EXAMPLE QUESTION

Try an example question.

Explore an example in the context of reviewing a code change against its acceptance criteria. It gives you a way to discuss the reasoning behind a candidate’s answer, alongside the Backend Developer assessment results.

Backend Developer: reviewing a code change against its acceptance criteriaWorkplace example

In this Backend Developer example, reviewing a code change against its acceptance criteria is part of the work. A change is ready for review only when the required automated checks pass. The implementation is complete, but a required check is failing.

A PRACTICAL GUIDE

Using the Backend Developer assessment.

What does the full assessment tell you?

This template combines multiple-choice questions in SQL, REST API, Logical Reasoning, Git, Linux; workplace situations in Problem Solving. It brings together evidence about coding knowledge, problem solving and reliable delivery, giving you areas to explore when reviewing a code change against its acceptance criteria.

How can you use the results?

Review each result against your vacancy’s responsibilities. Use a short task based on reviewing a code change against its acceptance criteria to explore practical application. Use a small code task. Ask them to explain their design, test edge cases and discuss how they would maintain it.

Which results matter for your vacancy?

  • SQLAsk how they would filter records, join related tables and verify a query result.
  • REST APIExplore requests, response handling and the checks needed when an API call fails.
  • Problem SolvingAsk them to break down a problem, compare options and explain their next step.
  • Logical ReasoningAsk them to explain the relationships and assumptions behind a conclusion.
  • GitDiscuss a branching workflow, a merge conflict and how they would recover an unwanted change.
  • LinuxDiscuss permissions, processes and the checks they would use to diagnose a service issue.

BEFORE YOU START

Your questions, answered.

Can I tailor this assessment to my Backend Developer vacancy?

Yes. Start with SQL, REST API, Problem Solving, Logical Reasoning, Git, Linux, then keep the tests that match your responsibilities. For example, use SQL to explore queries & filtering. You can add or remove tests before inviting candidates.

Does this assess practical Backend Developer work?

Candidates answer multiple-choice questions in SQL, REST API, Logical Reasoning, Git, Linux; 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 SQL included?

Checks whether candidates can write the queries the job needs, not just read them. Ask how they would filter records, join related tables and verify a query result. Review whether this area reflects the responsibilities of your vacancy before retaining it.

How long does this Backend 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.

Will I see a separate result for each test?

Yes. Review SQL, REST API, Problem Solving, Logical Reasoning, Git, Linux separately so a strength in one area does not hide a gap in another. Use the detail to focus interviews and relevant work samples. View the sample report.
