This is a popular interview question that tests your analytic and math abilities.
Cut the number in half because only men go to barbers. Then estimate how many times a man has to get his haircut (every six weeks or so). If a barber can only give a maximum of 15 haircuts a day (ballpark figure), calculate how many barbers you would need for 500,000 men to get a haircut every six weeks.

The number of barbers needed in a city of 1 million would depend on the demand for barber services, average number of clients per day per barber, and operating hours. A rough estimate could be made by considering the ratio of barbers to population in similar cities.
