A candle takes 1 hour to burn down. How would you measure 15 minutes if you had 2 candles?
Burn both side of the first candle and one side of the second candle. The first one should be burn at 30 minutes. After the first one is finished, the second one should left with half candle. If you want 15 minutes candle, burn both side of the second candle.
I can't remember specific questions. The behavioral ones can sometimes be tough so think of stories that can be applied to these types of questions.
