A 2020 Guide to Diagrammatic Reasoning Tests


If you’re bored of being stuck indoors during lockdown why not use the time wisely to improve your diagrammatic reasoning test skills, and increase your confidence before any upcoming interviews.

What is a diagrammatic reasoning test?

A diagrammatic reasoning test is designed to uncover your ability to infer rules from diagrams and apply these to different situations. They are also known as abstract reasoning or non-verbal reasoning tests, and are used by employers to assess your logical reasoning. The tests differ from numerical or verbal tests as they use shapes or patterns rather than words or numbers. Being able to think logically and solve problems is a key skill in all industries, so it is likely you will be asked to complete a diagrammatic reasoning test as part of most interviews or assessment days.

What is the format of diagrammatic reasoning tests?

Diagrammatic reasoning tests require you to find rules in shapes or patterns and apply these rules to a sequence. You’ll be required to answer multiple choice questions and you must identify the rule or continue the pattern in sequence. Candidates can find these tests difficult as they are much less likely to have come across them in real life, so it is imperative to practice diagrammatic reasoning tests to help you to prepare for your interview. Logical reasoning tests are similar but may use other forms or images as well as diagrams.

Why do employers use diagrammatic reasoning tests?

Diagrammatic reasoning tests assess your problem solving and logical thinking, both of which are hugely useful skills in all industries. The ability to gather information to form conclusions (inductive) or apply general rules to solve problems (deductive) will show potential employers you are right for the job, and also helps them decide who to invite for an interview. As these tests are more objective, they are less dependent on your educational background which can help ensure the hiring process is more diverse.

How can I prepare?

As these questions are more unusual than some numerical or verbal tests and do not rely on any prior knowledge, they may seem hard to begin with. It is important to practice many different diagrammatic reasoning tests to get a feel for how they are laid out. Practice the tests in exam-like conditions, using the one question per minute rule – if you are struggling on one question move onto the next one. Make sure you review any mistakes straight after answering the test to help you learn. It is important to read all instructions carefully and show your ability to problem solve under pressure when answering diagrammatic reasoning tests.

So give the memes a break and instead put your time to good use by practising these diagrammatic reasoning tests – the patterns and rules you’ll find are not only much more interesting, but they’ll improve your logical skills and confidence which will help you ace your interview and assessment day.
