The recommended approach to employee selection is built upon a total assessment of key factors important for success in work. Some factors which predict success, such as reasoning skills, are difficult to assess from resumes, application forms, or interviews alone. Therefore, online pre-employment tests are used to assess various skills using standardised tests which has been developed and validated to predict the success in fulfilling the requirements of the work.

Pre-employment tests are an objective, standardised way of gathering data on candidates during the hiring process. They can include testing of cognitive abilities, knowledge, work skills, and language proficiency. They help companies gaining insights into the capabilities and traits of prospective employees. Testing of applicants in pre-employment assessments can provide relevant information on a job applicant's ability to perform in the work place so that they provide tremendous value for organisations seeking to find the right talent. By adding pre-employment assessments to the candidate selection process, companies of all sizes can get a better handle on the vast pool of candidates applying to open positions.
