Ability tests look at the extent to which you are able to carry out various aspects of a job; for example, verbal reasoning and numerical reasoning abilities. Often employers are interested in the potential of an employee to do a task. In this case, they may use assessment methods that aim to simulate aspects of that task
Verbal reasoning is the ability to comprehend and reason using concepts expressed through words. A verbal reasoning test is a form of aptitude test used by interviewers to find out how well a candidate can assess verbal logic, and how successfully they can extract the correct meaning from written information.
The numerical reasoning test measures your ability to interpret, analyze and draw logical conclusions based on numerical data presented in graphs and tables. It is important to note that this numerical reasoning test (contrary to easier numerical reasoning tests) is not designed to measure your mathematical ability but your ability to use numerical data as a tool to make reasoned decisions and solve problems.
