...your answer is so far off the mark I'd recommend passing in an interview based on that alone. What kind of work do you do that requires regular detailed analysis of the complexity class of algorithms? It's been my experience that it's enough for an engineer to be able to say, "This algorithm will (not) run in an acceptable time for our expected input sizes," and that the precise definitions of NP complete and NP hard are best forgotten and looked up on Wikipedia when needed.
