A fresher was sitting in an interview. The interviewer said, "This is the last question of your interview. Tell me the accurate position of the center of this table where your resume is kept."
How can he answer this question? What will you have answered to such a question?
Put your finger confidently at a supposedly center point of the table and tell him that this is the exact center point.
The interviewer will ask, “How do you know this is the exact center?"
You can revert back that your last question was the previous question and thus you are not liable to answer further.
This is just a matter of being quick witted. The cleverer you are, the better the impression will be.
