I've felt like the candidate in the story before. For one company I interviewed with, the questions were all straight-forward. I finished 30 minutes early and they had no more questions to ask me. If the interview process can't differentiate from someone who is merely ok and someone who is amazing then the company will be likely filled with people who are only merely ok. That isn't a company I want to work for. Compare that to a place like Google where if you claim you are an expert at a language, they will have the language creator interview you.
