Two candidates have similar experience, and both performed well during their interviews. How do you decide between them? A recruitment test can help you assess a particular skill or observe how they approach their work. The key is choosing an exercise that reflects the job and knowing how to interpret the results.
What Is the Purpose of a Recruitment Test?
A CV provides an overview of someone's career. An interview gives you the opportunity to discuss their experience, motivations and expectations. But some practical skills are difficult to assess through conversation alone. A candidate might say they use Excel regularly without necessarily knowing the functions your team relies on.
A recruitment test allows you to assess these abilities through an exercise, questionnaire or practical simulation. For an administrative position, you might ask candidates to correct errors in a tracking spreadsheet. For a receptionist, a simulated customer interaction can show how they handle a request.
The value lies not only in the result but also in the candidate's approach. Do they check the information before answering? Do they recognise when something is missing? Can they explain their decisions? These observations provide useful material for further discussion during the interview.
However, no single test can accurately predict how someone will perform in their day-to-day role. It should provide additional information to support your decision, alongside their experience or a reference check, when relevant and conducted in accordance with applicable regulations.
What Are the Different Types of Recruitment Tests?
Not all recruitment tests serve the same purpose. Some assess existing knowledge, while others explore reasoning abilities or professional preferences. The format should therefore be determined by the skills you want to evaluate.
Technical skills tests
A technical skills test assesses practical abilities required for a position, such as using software, interpreting a technical drawing, understanding a procedure or drafting a document.
The exercise doesn't need to be complicated. If you're recruiting an administrative assistant responsible for tracking orders, a spreadsheet containing a few errors may be enough to start a discussion about their checking methods. There's little point asking someone to create a macro if that task won't be part of their job.
To design the assessment, start with a task the employee will actually perform. Then create a fictional version containing the necessary information. Candidates should be able to understand your expectations without already knowing your internal procedures.
Aptitude and reasoning tests
Aptitude tests assess abilities such as logical, verbal or numerical reasoning. They may involve interpreting data, identifying relationships between different pieces of information or solving problems.
Before choosing this format, consider its relevance to the position. What will the score tell you? Which ability are you trying to measure, and why is it important for the job?
The testing conditions also deserve attention. Misunderstood instructions or difficulties with the language used can affect performance. A low score should therefore be examined carefully before drawing conclusions about a candidate's professional abilities.
Personality questionnaires
Personality tests explore professional preferences and behavioural tendencies at work. They can provide a starting point for discussing how candidates organise their tasks, collaborate with colleagues or approach particular situations.
However, their results require careful interpretation. A questionnaire cannot establish with certainty that someone will get along with an entire team or always respond in the same way under pressure. It is also worth avoiding the temptation to favour candidates simply because they resemble existing employees.
If you decide to use this type of assessment, investigate its validity and the qualifications required to interpret the findings. In its recruitment guide, the French Data Protection Authority (CNIL) recommends checking the scientific validity of assessment methods and limiting evaluations to factors relevant to the position.
Practical work simulations
A work simulation places the candidate in a situation similar to one they might encounter on the job. This could involve handling a complaint, reporting an irregularity or organising several tasks.
This format provides more opportunities for observation. When dealing with an unhappy customer, for example, several responses might be acceptable. What matters may be the candidate's listening skills, the checks they carry out and whether their proposed solution falls within their responsibilities.
The simulation should be carefully structured. Prepare a fictional scenario, provide the necessary information and make sure the exercise can be completed safely.
| Your objective | Suggested assessment | Example |
|---|---|---|
| Verify a specific practical skill | Technical skills test | Correct errors in a tracking spreadsheet |
| Assess reasoning abilities | Aptitude test | Interpret numerical data |
| Explore professional preferences | Validated personality questionnaire | Discuss the findings with the candidate |
| Observe how someone approaches a problem | Work simulation | Handle a fictional customer complaint |
How Do You Choose the Right Test for a Position?
Before selecting a test, identify what the employee needs to know how to do from their first day. For an order picker, checking product references or spotting incorrect quantities may be essential. Learning to use your company's internal software, however, might be something they can do after joining.
This distinction should guide your assessment. Otherwise, you risk rejecting a strong candidate because they lack a skill you were planning to teach them anyway. Your job description provides a useful starting point for separating essential requirements from skills that can be developed during onboarding.
Next, identify a few specific criteria. "Being detail-oriented" is difficult to measure directly. "Checking product references, verifying quantities and reporting discrepancies" describes actions you can actually observe.
The assessment's duration should also reflect your needs. A short exercise may be sufficient to verify one technical skill. If you plan to use several tests, make sure each provides useful information. A lengthy assessment process requires time from both candidates and the employees responsible for reviewing their results.
Finally, test the exercise yourself before using it with applicants. Someone familiar with the job may notice unclear instructions, missing information or a valid answer you hadn't considered. If you're purchasing an assessment from an external provider, ask for evidence supporting its suitability for the position and target candidates, along with guidance on interpreting the results.
Four Examples of Recruitment Tests for Different Jobs
The following scenarios provide practical ideas for creating your own recruitment assessments. Each should be adapted to the role, the expected experience level and the resources available.
An order checking exercise for an order picker
Prepare a fictional purchase order and a list of picked items. Include a few discrepancies, such as an incorrect product reference, two missing units or an item added by mistake. Ask the candidate to compare the documents and identify the differences.
This gives you concrete information about their accuracy and checking methods. Someone who finishes quickly but overlooks several errors may not be better suited to the position than a candidate who takes longer to verify the details.
The discussion afterwards is also valuable. How did they approach the task? What would they do if a product reference were unreadable? The exercise provides insight into one specific responsibility but doesn't replace the assessment of other skills required in a warehouse.
A missing reservation for a hotel receptionist
A guest arrives at reception, but their reservation cannot be found in the records provided. Explain what information the candidate has access to, what checks they can perform and which decisions they're authorised to make.
Let them manage the conversation. Do they first try to understand the problem? Do they explain to the guest what they're going to check? When do they decide to involve a manager?
You don't need to expect a perfectly rehearsed response. A calm, clear and appropriate answer may be more valuable than a confident speech promising a solution the candidate cannot actually deliver.
Preparing for service in a restaurant
Present a list of tasks to complete before opening, such as preparing a workstation, checking equipment and reporting an issue. Ask candidates how they would prioritise these tasks, making sure they understand the scenario's constraints.
Their answers help you assess how they set priorities and interpret instructions. If a particular choice surprises you, ask them to explain it. They may have identified a dependency between tasks or understood an instruction differently.
Expectations should remain consistent with the experience level required. For an entry-level candidate, the discussion may mainly reveal what they already understand and which procedures they'll need to learn during onboarding.
Identifying defects for a production operator
Provide photographs of manufactured parts alongside a document explaining the quality standards. Some parts meet the requirements, while others contain defects. For a few items, the photographs should not provide enough information to reach a definite conclusion.
This last situation is particularly useful. Does the candidate acknowledge their uncertainty or make a decision despite missing information? In quality control, knowing when to request further checks can be just as important as identifying an obvious defect.
The exercise remains a document-based simulation. It allows you to observe the candidate's approach without exposing them to the risks associated with operating machinery.
How Can You Evaluate Test Results Beyond a Score?
Evaluation begins before the test takes place. If you wait until you've reviewed candidates' work or observed their performance to decide which criteria matter, you risk giving too much weight to whatever stood out at the time.
A simple assessment grid helps you apply consistent criteria across applications. For an order checking exercise, it might look like this:
| Criterion | What the recruiter observes |
|---|---|
| Understanding | Did the candidate understand the required checks? |
| Accuracy | Which discrepancies did they identify or overlook? |
| Method | How did they organise their checking process? |
| Reporting | Were the discrepancies clearly described? |
| Managing uncertainty | Did they verify information when unsure? |
You can assign scores if they're useful, but keep the observations that explain them. "Failed to identify two quantity discrepancies" provides more actionable information than "lacks attention to detail". You should also identify essential criteria: a good overall score shouldn't conceal a weakness in a skill that is fundamental to the role.
For comparisons to be meaningful, candidates should receive comparable instructions and resources, with any necessary accommodations. Explain the time limit, permitted documents and whether they can ask questions. Technical problems or interruptions should be recorded if they may have affected performance.
Take time to discuss the answers afterwards. A mistake may indicate a knowledge gap, but it could also result from an unclear instruction. Conversely, a correct answer may deserve further discussion to understand the candidate's reasoning.
These conversations help inform your recruitment decision. They can also support the successful integration of a new employee into the team. Areas requiring additional support have already been identified, allowing managers to tailor their initial explanations.
What Legal Requirements Apply to Recruitment Tests?
Candidates must be informed that they will be assessed and told which methods will be used. In France, Article L1221-8 of the Labour Code requires this information to be provided before testing begins. It also establishes the confidentiality of results and the requirement for assessment methods to be relevant to the intended purpose.
Information requested from candidates must have a direct and necessary connection to the position or their professional abilities, in accordance with Article L1221-6. Recruitment questionnaires should therefore not be used to investigate candidates' private lives.
Answers, scores and assessment reports also constitute personal data. Their processing must comply with the General Data Protection Regulation (GDPR), particularly regarding candidate information, access to personal data and retention periods. Results cannot be kept indefinitely.
Before introducing an assessment, make sure you can clearly explain its purpose to candidates: what you want to evaluate, how it relates to their future responsibilities and how the results will contribute to your recruitment decision. If these points remain difficult to define, the test probably needs to be reconsidered.
