I am a VP at a medium size company and I do plenty of interviews. I usually talk about what people are interested in and then ask one question:<p>&quot;You are in front of PC&#x2F;Mac&#x2F;Mobile screen, type www.cnn.com into browser, and press enter. A fraction of a second images show up on the screen... How? What happened? Tell me all you can from key press interrupts to underwater fiber cables&quot;.<p>This question never failed me. It always shows how deep does one go in their computer science adventures.
