Sometimes, all the contestants will miss a prompt, and Alex Trebek comes across as a bit smug or incredulous when reading out the correct response. ("No one? No one knew this? The correct response is....") I may have occasionally yelled at my television, "You have been the host for decades! They have to give you all the answers in order to run the show!"
And that's what it is when you think you're smart just because you know most of the answers on "Jeopardy!" The game is different when you're watching it (or hosting it) than when you're actually playing it competitively.
The interview processes that are designed to stress or fluster a candidate can make the divide between host and players even worse. There is nothing the candidate can do to get the interviewer fired. Almost anything the interviewer does can result in a no-offer.
