It is important to understand that companies typically use employment assessment tests as a means of gaining a deeper understanding of a candidate's personal behaviors and outlooks toward certain positions and to compare individual candidates. The test is likely only a single aspect of the application process and not a sign of any failures on a candidate's part.
Many companies use an employment assessment test in order to collect a standard set of data from all of its applicants and compare them without any external bias or qualitative information. If a company asks a candidate to take the test, it does not mean that it finds his resume or application lacking, or that it doubts his abilities. Before taking the test, candidates should relax as much as possible and focus on reading the instructions carefully in order to provide the most accurate answers. These tests frequently focus on a candidate's character and personality rather than on specific skills as a means to gauge how an individual reacts given different situations.
The employer may require candidates to take the test on site or allow them to take it from home through a website - either of which may take up to an hour, so test takers must allot for the appropriate time to take the test without rushing. Candidates should not try to answer the test the way they think the company wants them to answer, and instead use their own judgment and reasoning to address each question honestly.
