Numerical reasoning tests are a type of aptitude test commonly used in job interviews, especially in sectors where number crunching, data analysis, or financial knowledge is key to the role. These tests assess a candidate’s ability to understand, interpret, and apply numerical data. They can range from basic arithmetic operations to more complex data analysis and interpretation, involving graphs, tables, and statistical information. Understanding what these tests entail and how to prepare for them can significantly boost your chances of success in a job interview process.

Purpose of Numerical Reasoning Tests

The primary aim of numerical reasoning tests is to measure a candidate’s ability to work with numbers in a practical, real-world context. Unlike math tests in an academic setting, numerical reasoning tests are not solely about solving equations or performing calculations; they are about applying numerical understanding in a way that mirrors tasks in the workplace. Employers use these tests to identify candidates with strong numerical acuity and problem-solving skills, crucial for roles in finance, consultancy, engineering, and IT, among others.

Structure of Numerical Reasoning Tests

Numerical reasoning tests typically consist of multiple-choice questions where candidates are presented with numerical data in various formats, such as tables, charts, or graphs. The data must be analyzed to answer questions related to it. These tests are usually timed, adding an element of pressure that simulates the need to process information quickly in many job roles.

Key Skills Assessed

  • Data Interpretation: Ability to read, understand, and draw conclusions from data.
  • Mathematical Operations: Proficiency in basic arithmetic operations, percentages, ratios, and possibly more advanced mathematical concepts, depending on the job level.
  • Critical Thinking: Capacity to apply logic to solve numerical problems.
  • Attention to Detail: Ability to spot relevant data and ignore extraneous information.

Preparation Tips

Familiarize Yourself with Test Formats

Understanding the common formats and types of questions you might encounter is crucial. Many test providers have standard formats, and practicing with these can help you become more comfortable and efficient.

Practice Under Timed Conditions

Since these tests are usually timed, practicing under similar conditions can help improve your speed and accuracy. Use online resources or test preparation books to simulate the test environment as closely as possible.

Brush Up on Basic Math Skills

Ensure you have a solid grasp of basic math skills, including arithmetic, fractions, percentages, ratios, and reading graphs and tables. Although the math required is not typically advanced, accuracy and speed are crucial.

Analyze Graphs and Charts

Many numerical reasoning tests include questions based on graphs and charts. Practice interpreting various types of graphical data and extracting relevant information quickly.

Take Practice Tests

There are numerous resources available online, and tutorials. Taking these tests can help identify your strengths and weaknesses, allowing you to focus your preparation efforts more effectively.

Strategies During the Test

  • Read Questions Carefully: Ensure you understand what is being asked before attempting to answer. Misreading a question can lead to avoidable mistakes.
  • Manage Your Time: Allocate your time wisely, spending more time on complex questions without sacrificing the opportunity to answer simpler ones.
  • Use Estimation: When appropriate, estimation can save time and help you quickly eliminate implausible answers.
  • Don’t Get Stuck: If a question seems too difficult, move on and come back to it if you have time. It’s better to attempt all questions than to get bogged down by a few.

Common Challenges and How to Overcome Them

  • Time Pressure: Practice makes perfect. The more you practice under timed conditions, the more efficient you’ll become.
  • Complex Data Sets: Start by simplifying the data. Break it down into more manageable parts and focus on what’s relevant to the question.
  • Trick Questions: Always double-check your answers if time allows, and be wary of questions that seem too straightforward.

After the Test

Regardless of how well you think you performed, reflect on the experience. Consider what types of questions challenged you and why. This reflection can guide your preparation for future tests or interviews.


Numerical reasoning tests are a crucial part of the recruitment process for many roles, designed to assess a candidate’s ability to work with numbers effectively. Success in these tests requires not only a good grasp of basic math but also the ability to interpret data under time pressure. Preparation is key: familiarize yourself with the test format, practice extensively, and refine your test-taking strategies. By doing so, you can approach your numerical reasoning test with confidence, showcasing your numerical aptitude and problem-solving skills to potential employers.
