This depends on the level of the job you are assessing. With the non exempt applicant our assessment is used as an inexpensive screening tool before the invitation to interview. This saves huge amounts of time and insures that the managers are only interviewing the best qualified applicants. For exempt level candidates, we recommend you assess the finalist candidates after the first interview. This will help you select who makes the cut to the second interview while improving the quality of the next interview by helping the interviewer probe into areas of concern identified by the assessment. In some cases, assessment testing may indicate that the candidate is not a good fit and should not be interviewed. You are not obligated to evaluate every applicant that applies, but you must equally evaluate those who are seriously in contention for the job. Finally, pre-testing individuals who would otherwise incur travel related recruiting costs is usually a cost effective technique.
