The Interviewer: "You will choose to answer whether one hard question or 5 easier questions? Think carefully before you make the final choice "

The Candidate thought and made a final decision "I chose one hard question!"

"Good, good luck, you had your choice, here are your questions:  Which came first, the chicken or the egg?

 The Candidate appears happy and confidently answers: "It's the chicken!"

"Why?" The interviewer asked.

"Sorry sir, you promised me that only one given question. And maybe you will not ask me a difficult question too, won’t you? "

And then he was recruited.
