Once an Interviewer (I) asked a candidate (C) to have a good look at each and everything in the room. He gave him 2 minutes to do so and then asked him to leave and come back after 15 minutes.

C: may I come in sir.
I: Sure.
Candidate comes in takes his seat.
I: So, now tell me what has changed in this room in the past 15 mins.
Candidate looked at everything in the room. He was sure most of things were in the same place as earlier. After a couple of minutes of his intense looking he said –
C: The three hands of the clock (which was hanging right in front of him) – Hour, Minute and Second.
I: (Got impressed and smiled) Okay I wasn’t expecting that but your answer is correct as well. Let’s move on…
