Diagrammatic reasoning tests are similar to other tests such as logical reasoning, abstract reasoning and inductive reasoning. These tests are often used for the assessment of individuals applying for specialist jobs such as electricians, engineers, technicians in technology and developers etc. These tests are very popular within the investment banking industry.
These tests present questions in the form of diagrams where a number of rules apply. The test taker identifies the underlying patterns and rules that exist within the sequence of diagrams presented, and uses these to determine the correct answer which of course is missing.
These tests require the use of logical reasoning, and although the relevance or type of test used for a job that requires this type of reasoning may vary, it is based on the same ability type. Financial institutions use logical reasoning tests in enormous volumes for recruitment purposes. If you are applying for a job at a bank, then it is highly recommended that you practise this type of test.
