When you are hiring a data center employee, you are hiring someone who’ll be responsible for expensive hardware, critical software and sensitive data. According to a US Department of Labor 2003 report, an average cost of a bad hiring decision can equal 30 percent of the hire’s first year of salary. But this might be a very conservative estimate. In a data center, an employee’s mistake can cost you hardware failures, software corruptions, security vulnerabilities and data loss. So it’s crucial to hire the right person for the job.
