Interview Techniques you should have

Interviewer said,"I shall either ask you ten easy questions or one really difficult question. Think well before you make up your mind!" The boy thought for a while and said, "My choice is one really difficult question."" Well good luck to you, you have made your choice! Now tell me this. What comes first, Day or Night?" The boy was jolted into reality as his admission depended on his correctness of his answer but 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 a SECOND difficult question" He was selected.
