I went for an interview once where the guy asked me "Define Ethernet". I went "Huh? Who cares what the definition is. I've been building networks for 7 years; Give me an IP range, I'll give you the correct subnet. Give me specific questions about the Do's and Don'ts and I'll answer those. But who gives a flip what the definition is?" They did, I answered, and was offered the job 2 weeks later. I hate stupid interview questions.
