O2 Numerical Reasoning Tests

The O2 numerical reasoning tests evaluate your ability to interpret information from graphs, charts, and tables and perform essential mathematical calculations, such as addition, subtraction, multiplication, division, ratios, proportions, and averages. These tests are designed to assess arithmetic skills with a focus on speed, accuracy, and attention to detail. An applicant’s numerical reasoning is a very important skill in a data-led customer-oriented environment like O2. The exact format and content of these tests also varies but practising numerical reasoning tests beforehand is great for familiarising yourself with the general question style and improving your performance.

Prioritise mastering essential mathematical skills, including percentages, ratios, averages, and the ability to interpret information from graphs and charts. Effective time management is critical—tackle simpler questions first and avoid dwelling too long on challenging ones. Where calculators are allowed, use them wisely to save time and ensure precision.

O2 Application Process

Stage 1 - Online Application Form

The O2 application process begins by completing an application form on the O2 Careers website. Candidates are required to provide personal information, educational background, and have the option to upload a CV. They don’t specifically request a CV as they look to make the application process as easy and accessible as possible. The main objective is to put across any relevant skills / experience you might have for the role you are applying for.

Stage 2 - Online Tests

The next stage of the O2 hiring process involves completing online tests. The tests a candidate is asked to take is role-dependant but all applicants will have to complete a situational judgement test which will likely contain elements of the other tests within it. The tests they use are usually SHL supplied but this can vary between regions. The possible tests you may be given are:

  • Numerical Reasoning Tests
  • Logical Reasoning Tests
  • Verbal Reasoning Tests
  • Situational Judgement Tests

Stage 3 - Telephone Interview

After completing the online tests, you will take part in the O2 phone interview, during which you will be asked some competency and scenario-based questions. This is a chance to make an impression and showcase your skillset through past experience. You may also be asked to complete a video interview beforehand which will require you to begin with a written long answer question that you can use to highlight your competencies and motivations.

Stage 4 - Coaching Call (Non-Assessed)

This is a quick one-on-one conversation which helps a candidate to prepare for the final stage of the O2 hiring process. It isn’t assessed and is more used to put an applicant at ease and feel more comfortable going into the final stage.

Stage 5 - Virtual Assessment Centre

The final stage of the O2 application process is an invite to the Virtual Assessment Centre. The activities you complete on the day can vary but you will be provided with this information before attending. These activities are completed online and may include a group exercise, interactive role play exercise and interview. After this stage you will hear back regarding an offer.

About Other O2 Psychometric Tests

O2, a leading telecommunications provider, is known for its commitment to innovation, customer service, and sustainability. The company offers a variety of graduate schemes in areas such as Marketing, Technology, Business Operations, and Data Analytics. To ensure they select the best candidates, O2 incorporates psychometric testing as part of its application process. These assessments typically include numerical reasoning as explained above, verbal reasoning to test comprehension and communication abilities, logical reasoning tests to evaluate how candidates approach problem-solving tasks and situational judgement tests (SJTs) to assess decision-making and alignment with O2’s core values, such as customer focus and collaboration. The tests, generally provided by SHL, help O2 identify graduates with the potential to excel in a fast-paced, customer-driven environment.

O2 Logical Reasoning Tests

O2 may employ logical reasoning tests which aim to assess a candidate’s ability to recognise patterns, solve problems, and think critically in unfamiliar scenarios. These tests often involve analysing sequences, completing patterns, and drawing logical conclusions from the provided information. Designed to evaluate problem-solving abilities, they challenge candidates to interpret abstract and complex data within a strict time limit. These tests are a big factor in advancing to the next stage and the multiple-choice format requires strong attention to detail and quick decision-making, such as identifying the next or missing shape in a sequence. Patterns may involve rotations, shifts, or other abstract rules governing shape arrangements. Be sure to check which tests your scheme requires of you and to practise as many logical reasoning tests to give your self the best chance at this aspect.

O2 Situational Judgement Tests

The O2 situational judgement tests are present in the O2 application process for all roles. They look to assess a candidate’s decision-making, problem-solving, and alignment with the company’s core values. Candidates are presented with workplace scenarios and possible actions which need to be rated based on how effective they are. These tests evaluate how well an applicant’s behaviour aligns with the company’s expectations and their suitability for the work environment. O2 analyses responses to identify key qualities in candidates, and aligning answers with the company’s values significantly increases the likelihood of progressing to the next stage.

O2 Numerical Reasoning Test FAQs

Numerical reasoning tests are role-dependent. They are generally required for positions involving data analysis or financial decision-making, but situational judgement tests with numerical elements may be included for all roles.

O2 numerical reasoning tests assess a candidate’s ability to interpret numerical data from graphs, charts, and tables, and solve mathematical problems like percentages, ratios, and averages. They are used to evaluate arithmetic skills crucial for roles in O2’s data-driven and customer-focused environment.

These tests, often supplied by SHL, feature multiple-choice questions focused on practical scenarios. They may include interpreting data, performing calculations, and analysing trends. While the exact format varies by role, the tests typically last 20–30 minutes.

To prepare effectively, practice similar numerical reasoning questions to build confidence and familiarity with the format. Focus on mastering mathematical concepts like percentages, ratios, and data interpretation. Practice time management by prioritising easier questions and using a calculator efficiently.

Yes, calculators are allowed for O2 numerical reasoning tests. Using a calculator strategically can help you save time and maintain accuracy during calculations.

In addition to numerical reasoning, O2’s psychometric tests may include logical reasoning to evaluate problem-solving skills, verbal reasoning to assess comprehension and communication, and situational judgement tests (SJTs) to test decision-making and alignment with O2’s values, such as customer focus and collaboration. Each role may require a combination of these assessments.
