The creators of ``Undercover Boss'' are behind this unscripted TNT series, which gives the popular CEO-in-disguise premise a bit of a twist. ``Inside Job'' puts candidates for six-figure executive positions through a unique screening process. Four people in each episode live and work together during a weeklong job interview, but what three of them don't realize is there is a spy in their midst -- one of the ``candidates'' is already an executive with the hiring company. That allows the insider to closely watch the other three and report the findings -- good and bad -- to his or her boss. As the week concludes, the insider is revealed and chooses the most deserving applicant to be offered the job.
