The next step is to sort through your candidates and select the best candidate. Interviewing is the standard for determining if the person might be a good fit for your company. Formal testing helps to assert whether their claims of certain abilities and skills are valid, although there are legal issues that can arise if you use invalid tests. The other challenge to testing is that some people are really bad at writing tests, and you might pass on a candidate who could be a great fit for the company and has the ability to learn what is needed just because they do not test well. Reference checking, which is becoming more and more difficult due to privacy concerns, is still relied upon and necessary to validate a person’s work experience and their formal education.
