Diagrammatic Reasoning Tests

Diagrammatic reasoning tests are all about applying logic to a series of different flow charts or diagrams.

  • What are diagrammatic reasoning tests?

    Diagrammatic reasoning tests use patterns and shapes rather than numbers or words to test your logical thinking skills.

    Throughout the test, you’ll be shown a series of different puzzles that require you to select an answer that completes the puzzle, or follows the same logical sequence. You’ll have about one minute to answer each question, so thinking quickly and clearly is crucial.

    Many employers use diagrammatic reasoning tests to tease out which candidate applying for a job has the skills needed.

  • Why do employers use diagrammatic reasoning tests?

    In the tech industry, thinking logically and demonstrating an ability to follow sequences is crucial. As a result, more and more employers in the technology sector will ask you to complete a diagrammatic reasoning test as part of your application process.

    Excelling at the test also shows employers you’re able to cope under considerable time pressure - another skill that’s highly valued by big corporations.

    You may not have taken a test like this before, so practising as many diagrammatic reasoning tests as you can before the big day is really important.

  • What is the diagrammatic reasoning test format?

    With very little time to do the test, you’ll need to average completing one question per minute (although this can vary from test to test).

    Each question will require you to look at a series of diagrams, patterns or shapes, before asking you to select the diagram, pattern or shape that follows the sequence in practice.

    This type of test could be unlike anything you’ve ever done before, so it’s worth taking some practice tests beforehand to gain a better understanding of what’s being asked of you, not to mention improve how quickly you can answer each question.

  • What skills does diagrammatic reasoning test?

    The test examines how quickly you can work out the logic that connects a series of patterns. Logic is a highly valued skill, especially in the technology industry, and employers want to know the people they’re hiring have the expertise needed to succeed.

Diagrammatic Reasoning Tests Tips

Familiarize with Flowcharts

Begin by acquainting yourself with different types and formats of flowcharts and diagrams. Understanding the basics of flowchart symbols and the logic behind sequence diagrams is essential. Get comfortable interpreting these elements quickly, as it will form the core of diagrammatic reasoning challenges.

Spot the Patterns

Diagrammatic reasoning tests are all about identifying patterns and rules. Practice observing how changes in one part of the sequence affect another, and try to predict outcomes. The more patterns you've seen and worked with, the less daunting these questions will become.

Think Logically, Not Intuitively

When answering diagrammatic reasoning questions, rely on logic rather than gut feeling. Make sure that each conclusion you draw is supported by the information provided in the test. If it doesn't add up logically, reconsider your approach to the problem.

Time Management

While it's important to work swiftly, accuracy is key. Pace yourself so you have enough time to analyze each diagram and respond to each question with care. You can build up speed with practice, so make ample use of Techtest's practice exams to improve your pacing.

    The test itself: it was challenging and not like any other I've taken, yet the skill felt familiar, as one I think I have a knack for and use frequently, but haven't had a way to describe or pursue. Design: clean, simple layout/design and flow.
