Do you know how many sparrows are there in India?


Guesstimates are questions like, “How many cricket balls will fill up this room?” These questions are common for roles requiring analytical and problem-solving skills. The interviewer will evaluate how you react to a non-standard problem, break it into parts, structure an approach and then use basic maths or general knowledge to arrive at an estimate.

The interviewer does not want you to pop out a random number but wants you to vocalise your thought process. So, you could possibly start by saying that you will estimate the volume of the room and the volume of a ball to arrive at the answer and then work out each component. You are permitted to ask questions, make intelligent guesses and request a pen and paper. Find similar questions and answers online and practice guesstimating aloud.
