Background checks can be one of the most nerve-racking activities related to getting a new job. In many cases, it’s not that you have anything to hide, but it’s just that the propensity for error – either by a human or machine – can have some serious ramifications.

Think of it as a sneak peak of what a potential employer might see when you go to apply for a job.
