Interview

This actually happened in an IIM Ahmedabad Interview...
This is a real episode which happened during the interview rounds of IIM for the class of 2004.
Interviewer said I shall either ask you ten easy questions or one really difficult question. Think well before you make up your mind!
The candidate thought for a while and said, My choice is one really difficult question.
Well, good luck to you, you have made your own choice!said the interviewer. Here is your question: What comes first, Day or Night?
The boy was jolted into reality as his admission depended on the correctness of the answer to that one question.
He thought for a while and said," It's DAY sir!"
"How?" the interviewer asked.
" Sorry sir, you promised me that you will not ask me SECOND difficult question!"
He was selected for IIM!
