1. How many gas stations are there in the USA?
If you are going to senior Microsoft programmers, get ready to evaluate the size of markets on the fly. This question has already managed to fill my mouth, and yet - how can I answer it? Start by assessing how many gas stations there can be in a city with a population of 30 thousand people, and then scale it to the entire US population (about 314 million). For the cheat sheet: by 2008, there were 117,000 gas stations in the States, according to the US Census Bureau. About 1 refueling per 2.5 thousand people.
2. How do you check the calculator?
This question was asked of candidates for the position of software engineers at IBM. The question is rather strange and with subtext. You can answer something like this:
“I would check the accuracy of the calculations by checking whether the output is consistent with the input. And I’d check the basic functions of the device - the power button, delete previous calculations, and so on, to make sure there are no errors before starting the calculations. ”
The higher the position you are applying for, the deeper you will have to plunge into the world of calculators.
3. How many golf balls are there in Florida?
IBM asked this question to operational specialists. To answer this question, remember the US population. Calculate the percentage of golf. Then the number of balls each player uses for the year. Estimate the percentage of players in Florida. Well, add 50% of old or unused balls. We practice: according to data from production facilities, there are 2 billion golf balls in the USA, plus another 1 billion old or unused. Florida accounts for about 7% of all US golf courses, so we can say that Florida has 210 million golf balls.
4. How many streetlights in New York?
If you failed in an interview with IBM, then do not go to JPMorgan Chase, because they also ask questions about estimating the size of markets. Estimate the number of horizontal and vertical blocks on a map of Manhattan, and then the number of lights in each of the blocks. It remains only to multiply by five to take into account the lights in all five areas of the city. To check: the official website of the city says about 300 thousand street lamps.
5. An apple costs 40 cents, a banana costs 60 cents, and a grapefruit 80 cents. How much is a pear?
Epic Systems, a technology company that cares about the health of employees, examines project managers and implementation consultants with fruit puzzles. For one of the possible answers, one must turn to the original language, because the whole secret is in the number of vowels. If you pay 20 cents for each vowel, then you pay 40 cents for an apple, 60 cents for a banana and 80 cents for a grapefruit. Therefore, a pear will cost 40 cents.
6. How many plastic bags do you need in the US?
Those wishing to take an internship at Bain & Company will find a really tricky question on market analysis. The difficulty is that simply analyzing the population is not enough. It is necessary to take into account the needs of ordinary citizens, businesses, government agencies and so on. Unwind reasoning as long as it takes to quench the thirst for knowledge of the interviewer. Remember to note that plastic bags are prohibited in some states. According to recent studies, more than 380 billion packages are used annually in the United States.
7. Describe the Internet for a person who has just stepped out of a 30-year-old coma.
Applicants for the position of analyst at Digitas must describe what they use day after day. If you can discard thoughts about the delusional nature of such a scenario with a coma, then think a little. You can compare the Internet with something that a person knew 30 years ago, for example, from science fiction films. If a person does not remember anything at all, then add a little humor to your story. It is possible that the interviewer will not be offended by your attempts to gain his favor.
8. Which of this information is most useful for calculating the number of people working in a thirty-story building: the number of cars in the parking lot, the number of diners in the cafeteria, or the number of people on the 11th floor?
American Express screened out candidates for the position of strategic analysis and testing manager.
Without additional information, each of the options is insufficient to answer. If possible, check the information about the building: in the suburbs or in the center. Then we can assume that people get to work by public transport, and not by car. Otherwise, the best idea of the spaciousness of the building is given by information on the number of people on one floor. The main thing here is to be able to substantiate your answer.
