Remains me of a recent almost interview I almost went through. I have 15 years of experience in IT and basically over past 7 years I built two large healthcare-related CMS systems. The company found me through one of clients that uses my product for 5 years and is very happy with the value 2 cost ratio.

So I go in and first question I hear. "can you describe how is TCP/IP built". This is for web development position, you know code igniter, php, jquery, that kind of stuff. I looked at them for about 45 seconds, got up and said "thank you for your time" and left before they had a chance to say anything.

Dude, wtf, are you serious? Its not like i couldnt remaind something about tcpip from the times of my b.d. 10 years ago, but seriously unless we are going to invent new transportation protocol for the whole human civilization to use, why on earth would you ask me that, when you hiring me to be a web developer. What a joke!
