Pre-employment and background checks. Our professional background checks help mitigate the risk of bad hires and poor employee performance. MVSI is the partner of choice to provide the additional resources and expertise to augment your hiring processes accurately, quickly, and cost effectively. MVSI pre-employment services count as the best in the industry, and our reference checking and verification services are provided by actual professional verifiers, highly experienced, and professionally trained. Verifying a candidate is a professional skill developed over time. It takes experience to handle inaccuracies or discrepancies without offending, but still be able to get to the heart of the issue! More than that, unlike many companies that simply read from a list of questions, our verifiers listen, quantify, and every check is an individual exercise to ensure our clients have accurate information on who they are employing.
