The first season, the cover story was that a documentary was being shot about someone who had been laid off trying to re-enter the workforce.
This season, they're using the two employees vying for a job.
To me, the employees seem truly surprised at the end. Some don't even recognize the CEO as the employee they worked with. And some of them seem really torn up about having to choose one "contestant" over the other for the job.
A cruise employee did recognize the CEO on that episode, and that was shown on the show. The bowling alley CEO was recognized by the parents of the franchise owner - and that was shown as well.
