Ability tests are part of assessment tools used by hiring managers and HR teams to identify the problem solving ability of an individual
Here are some of the benefits of using ability tests when recruiting for your jobs:
Standardized - Traditional cognitive tests are well standardized ensuring that there's less bias in hiring
Reliably scored - Most tests are multiple choice, sentence completion, short answer and require the assessees to define the scoring scheme. Due to this the results are directly comparable.
Candidate friendly - If designed well and by providing a good test environment, companies can ensure that candidates are more comfortable in answering.
