Many technology companies bemoan how difficult it is to find good employees. A new study suggests the companies themselves might be partly to blame.
At issue is a widespread reliance on what is known as the technical interview process. In addition to the usual vetting of credentials seen in many industries, technical interviews typically subject job candidates to layers of intense testing. Generally, such tests evaluate critical thinking and problem-solving skills. They can include brainteasers and complicated technical problems unrelated to actual on-the-job roles and responsibilities.
The trouble is this: Candidates often get so flustered from the pressure and the mechanics of the interview that their performance is significantly hindered.
Companies that rely on these stressful tests are eliminating potentially qualified candidates—to their own detriment, says Christopher Parnin, assistant professor of computer science at North Carolina State University and senior author of the study, which was published in November. This is particularly unfortunate, Dr. Parnin says, given the availability of other, less stressful and perhaps more appropriate testing metrics.
