One of the most widely used companies is SHL. If you're applying for a job in most parts of the world there is a good chance your employer uses SHL tests, particularly so in the UK.
SHL has a wide range of psychometric test packages tailored for specific positions and levels, and they come in a large variety of test batteries. These tests can include the SHL Management and Graduate Item Bank (MGIB), the SHL Critical Reasoning Test Battery (CRTB), the SHL Information Technology Test Series (ITTS), the SHL Applied Technology Series (ATS) and the SHL Personnel Test Battery (PTB) to name but a few. All of these tests are made up of specific numerical, verbal and other cognitive ability test questions.
In addition SHL also has a series of tests known as "Verify" tests. These are shorter, more concise versions of their more comprehensive batteries. The Verify tests are usually administered online and can be used both at early stages of recruitment to sift through initial candidates or during later stages in order to verify the results of previously taken tests.
The type of Verify tests SHL uses are Verbal, Numerical, Inductive, Checking and Calculation.
Here are some of the companies that use SHL's test services: Marks & Spencer, Target, Microsoft, Sprint, General Mills,Time Warner Cable, UnitedHealth Group, Xerox Corporation, Vodafone, Danone, and Barclays.
