Prepare for Sequestration

Yay! A reality show is interested in you. You just need to fly to L.A., New York or some such locale and go through the final casting process, where the show's producers will whittle down the potential candidates to those who will actually make it on the show. It might sound like fun — a week or two away from home — but you may be confined to a hotel room for most of the time, unable to use the Internet or even make phone calls. Contestants on "The Bachelor" say you have to stay in your hotel room during the casting process, and also during the week leading to filming. A past contestant on "The Biggest Loser" says not only was she placed in a hotel room, but staff took away her hotel key card [sources: Callahan, Rees].

Sarah Monson, a casting expert, affirmed to Film Industry Network that people who advance to the final casting round are likely put up in a hotel, where they're instructed not to speak with anybody, even if it's idle chatter that has nothing to do with the show. Besides meeting with network big-wigs who may grill you, you'll likely have to undergo mental, physical and drug testing. For some, it can be a lonely, exhausting process.
