Well these questions are really strange for asking by a big company but still they always ask something that shows them the hidden talents of a person and how quickly they can solve a problem in the real working conditions,

But most of us give wrong answers because we got over excited or over feared by the interviewer,so the best thing to get success into any interview is just keep yourself calm and don't try to pretend someone else just maintain your own comfort zone and try to stay calm and relaxed.😇😇
