This is part of a personal challenge to become a better interviewer and problem solver.
Question: How many restaurants are there in San Francisco?
Learnings:
- The candidate used how often people eat out as a basis to their guests.
- They also took a proportion of the population and gauged their behavior.
- They estimated the number of tables in a reataurant and how often they “turn” them (eg. 2.5 times a day, lunch, dinner and some other reason).
- They also cross-checked their estimate with a surface based estimation using teh surface of San Francisco, how many blocks there are and how many restaurants per block (about 1 for every 5 blocks).
