You want a story? I'll give you a good interview question that made me crazy for days.
I was on a technical interview and the interviewer asked me this:
"Pick a state and pick a number." (I said New Jersey and 200,000)
"You are in a city in New Jersey that has a population of 200,000 people. How many barbers are there?"
Okay, I promise, I'm not going to rant on how these pompous idiots torture people who are just looking for a job with insane questions but I'll tell you that the object of the question is to see how you think.
My answer was, "Given that hair grows at approximately half an inch per month and that most people don't feel they need a hair cut until their hair reaches an inch longer than normal then people go to the barber once a month. The average work day is eight hours including lunch (as defined by OSHA) and it should take an average barber approximately a half hour to cut one person's hair - meaning that they can cut 14 people a day. Assuming that people are going to have their haircut locally and that their are a percentage say (10%) of people who are bald and don't require haircuts that 20,000 people don't go - leaving 180,000 who require haircuts every two months or 61 days. 1 barber can cut 854 people for two months. 854 into 180,000 is 210. Approximately 210 barbers for that city."
