The main advantages of psychometric testing are that it measures every applicant in the same way, it predicts job performance better than a CV alone, and it lets employers assess large numbers of people quickly. Candidates benefit too: a strong result can open doors that a CV might not, and the experience can show you where your strengths lie. Testing works best alongside interviews, not instead of them.
To see the kind of test these benefits come from, try a free psychometric test. The rest of this guide sets out the benefits for each side, and the limits worth knowing about.
Benefits for employers
Consistency. Every applicant answers the same kind of questions under the same conditions, and is scored the same way. That makes comparisons fairer than reading CVs, where the result can depend on who reads them and in what order.
Better prediction. Well-designed ability tests are generally found to predict job performance more reliably than CVs or unstructured interviews. They measure how well someone handles new information, which matters in most jobs and is hard to judge from a list of past roles.
Efficiency at scale. A popular graduate scheme can attract far more applicants than any team could interview. Online tests let an employer assess everyone at an early stage and spend interview time on the people most likely to succeed.
A wider talent pool. Because tests measure reasoning rather than background, they can help employers look beyond the usual universities or previous employers, and find capable people whose CVs would not have stood out.
Better interviews. Personality questionnaires give an interviewer a starting point. If a profile suggests someone prefers working alone, the interviewer can ask how they handle team projects, rather than relying on generic questions.
Development after hiring. The same kinds of tools can help existing staff understand their working style, plan training and work better in teams.
Benefits for candidates
A chance on merit. A test scores what you can do on the day. If your CV is thin, your degree is from a less well known university, or you are changing career, a good result is evidence an employer can act on.
A fair and open process. You know you are being assessed on the same basis as everyone else, and the format is usually explained in advance. That is easier to prepare for than an unstructured process where you cannot tell what is being judged.
A realistic preview of the job. A test built around the role, such as a numerical test for a finance job, gives you a feel for the kind of thinking the work involves. If you find that thinking draining, that is useful to know before you accept an offer.
Insight into yourself. Practice and feedback show which kinds of reasoning come most easily to you, which can help with career choices. Our guide to psychometric career tests covers this side in more detail.
You can prepare. Unlike a CV, which reflects years of history, your test performance can improve in a few weeks of focused practice, mainly by getting used to the formats and the time pressure.
Limitations to keep in mind
Psychometric testing has real limits, and a balanced view helps both sides use it well.
- Unfamiliarity. Candidates who have never seen these formats can underperform at first. Practice narrows that gap, which is why employers often publish example questions.
- Test anxiety. Timed tests are stressful for some people, and nerves can lower a score.
- Fairness depends on the choice of test. A test that does not match the job, or that disadvantages some groups without good reason, is neither useful nor fair. Employers should check that their tests are relevant and monitor their outcomes.
- Personality answers can be shaped. Some candidates try to give the answers they think are wanted. Well-built questionnaires check for consistency, and honest answers usually serve candidates best anyway.
- Not the whole picture. A test measures some important qualities, but not experience, motivation for a particular role or how someone will get on with a specific team. That is why tests are usually combined with interviews and other evidence.
Getting the most from testing as a candidate
The benefits only reach you if the test reflects what you can really do. That means turning up familiar with the format, not meeting it for the first time. Read about psychometric testing in recruitment to understand how your results are used, then follow the steps in how to pass a psychometric test.
If you have a disability or condition that could affect how you take a test, ask the employer about reasonable adjustments as early as you can.
The simplest first step is to sit a timed psychometric practice test and read the worked solutions afterwards.
