Interviews aren't funny, like at all. There's nothing remotely entertaining about getting grilled about your life and being expected to lie and embellish everything you say. It's pretty much a contest so see how good of a bullshitter you are compared to the next guy that's going to be sitting in that seat 15 minutes later. If embellishment and bullshitting is expected, why not do away with that whole expectation and just let candidates be themselves? 

Anyways, that's the reason I love these things. Nothing's better than lampooning the entire strange experience.
