# Interview: Give you 10 people statistics about how many light bulbs there are in Beijing? Look at these three answers, netizens: silly

The second answer: I think its a test of my ability to do fast statistics. I will divide the city into 10 blocks, each responsible for a block, design a good statistical form, recruit some volunteers to the university, organize undergraduates to push the floor with the minimum cost, and make statistics for each resident and public building door to door. Such data is the most true and accurate.

The third answer: I think the information age should use Internet + means. I choose 5 programmers to develop the bulb statistics APP, 5 people push APP, take the activities of downloading prizes, and so on, as long as they carefully fill in their own family and companys bulbs, there are prizes to stimulate the public to fill in the number of bulbs.

Interviewers like to write from the media and send the above answers to the Internet. After viewing them, netizens follow the posts one after another: brainstorming, boredom.

So what is the standard answer to wr? In fact, it really shocked people. The purpose of WR is to examine the applicants estimation ability, but it has no other meaning. If you encounter such interview problems, use your brains and quickly estimate them. Wwr recruits technicians, requiring quick estimating ability. Statistics of the number of windows in a city, unless the number of one, otherwise, never get accurate data. Because there is no organization that specializes in statistics. Besides, whats the significance of such accurate statistics?

So the correct answer strategy is:

Im sorry, interviewer. I dont need 10 people. I can answer you now. The city has about 10 million households or residential units, each with about 20 light bulbs and about 200 million light bulbs for residents; about 20,000 public buildings, each with an average of 10,000 light bulbs, about 200 million light bulbs; 20,000 kilometers of streets, about 100 million street lights, colored lights and neon. Rainbow lights, etc. So there are about 500 million light bulbs in the city.

Do you have any good ideas? Lets talk to each other.
