Microsoft classic interview questions (with answers)

The reason for a famous brand is that even recruitment is different. Microsoft's recruitment has always been a topic of discussion, saying that it has all sorts of difficulties and that it has its own advantages. Here, I try to take out several questions that Microsoft has used in the recruitment process for your comments to see if these questions really want to examine the quality of the candidates.

Generally, Microsoft has four types of interview questions: Riddle questions, mathematical questions, intellectual questions, and application questions. Here are two questions about riddles:

1. How many cars are there in the United States?

2. Insert the car key into the door. In which direction can the car lock be turned on?

Xiao Zhang (99-level student from School of Management of Fudan University): These two questions are not difficult. I think he may just want to examine the applicant's adaptability, that is, the ability to quickly respond to nonstandard problems in a short time.

Mr. Sun (an employee of a large multinational company): Obviously, these are two open answers. I think it is to check whether the applicant can think logically about a problem and quickly find a solution to the problem through this kind of thinking. As for the answer, the questioner obviously does not care about it.

Associate Professor Yan (Fudan University): The problem is open, but the direction is also obvious. Whether the applicant can respond to unexpected questions in a short period of time and answer such questions logically. The questioner also hopes to get an unexpected answer. Many people collect such questions on the Internet to prepare answers, which clearly violates the intention of the questioner. Duplicate answers are not good answers.

The following are two mathematical questions:

1. How many digits does 1000 have? Why?

2. Compile a program to calculate the sum of quality, for example, F 7 = 1 + 3 + 5 + 7 + 11 + 13 + 17 = 58.

Xiaolu (99-level student in the Department of Physics, Fudan University): Mathematics questions and application questions are the most obvious class of questions in Microsoft interviews. These questions are used to evaluate the examinee's mathematical and computer skills.

Ms. Shi (Senior Consultant of a consulting company): Microsoft is a computer software company. Of course, its employees are required to have certain computer and mathematical skills. This kind of ability will naturally be examined during the interview. Microsoft's above interview questions examine the degree to which candidates can master basic knowledge, the ability to apply basic knowledge, and even the basic principle of computer. Therefore, such an interview question is indeed very "Spicy", enough to find the right people.

The following are smart questions:

1. It takes an hour to burn an uneven rope. How can I use it to judge for half an hour?

Xiao He (00-level master's degree in computer science at Fudan University): I think it is hard for me to understand this part of Microsoft's questions. Most of the time I don't know what he wants to examine me, sometimes I even think it is just a sharp turn. However, I remember Li Kaifu said in the CCTV program that their research content is the plasticity of candidates.

Mr. Shi (a staff member of a large state-owned enterprise): I think this part of the problem is very random, mainly to examine the applicant's IQ, but because of the different problems, there are different research directions, for example, the first question is the applicant's reverse thinking ability, and the second question is the applicant's observation ability and degree of detail.

Mr Yu (personnel director of a foreign company): I don't know what Microsoft intends to answer these questions. However, in my opinion, the best way to study the questions is Microsoft's interview. Not only are the points pointed to differently, but the answers to the questions can sometimes be enlightening. For example, if you can find the answer to the second question above, it will help you understand the combination of Enterprise Resources and play different roles after optimization. Different managers will use different combinations, and of course the results will be different!

76: the stewardess allocates items
  
On a plane, there is an aisle in the middle, with seats on both sides, and three people in each row. Two flight attendants A and B are responsible for one side and each passenger is assigned travel items.
  
At the beginning, a gave 6 copies to the passengers on the right. At this time, B came to her and said that a should be responsible for the passengers on the left. So a is issued to the left, and B is assigned to the right.

After the passengers issued the goods, they helped a send 15 more, and the last two ended their work at the same time.
  
Q: Who sent more messages from a and B? How many copies are sent?

Answer: It must have been a lot of B,
Analysis: The owner of A and B respectively states that the number of each owner is the same. A is sent to the right and his own
Assume that a total of any number greater than 15, for example, 20, should be calculated as follows: (20 + 15)-(20-15) = 30
Simple math problems?

77: plane ticket
  
The travel agency just booked a plane ticket for three passengers. The three passengers are Dutch Cole, Canadian Berto, and British danpi. The three of them went to the Netherlands

In Canada, I went to the UK. It is reported that Cole does not intend to go to the Netherlands, danpi does not intend to go to the UK, while Berto does not go to Canada or the UK.

71. Canned weighing
  
Deliveryman A, who works for a can factory, sent 10 boxes of canned pineapple to a food company. Each can has a weight of 800 grams and 20 containers.
  
Just as he had delivered the goods and was about to return to the factory, he received a call from the factory, saying that one of the 10 boxes had been mixed into the defective product due to a machine problem,

Each can lacks 50 grams of weight and the deliveryman needs to send the box back to the factory for replacement. But how can we find out which box is defective? Of course

Scales, but not at hand.
  
At this moment, he suddenly found that not far from the road there is a machine automatically weigh the weight, that is, invested in 1 Yuan coin can weigh a weight. His pocket

There is just a 1-dollar coin. Of course, only one energy. So how can he make full use of this only one opportunity to find the box of products that do not meet the specifications?

In a rural school, S, a recently graduated male math, was lucky to be favored by both female A and B. S is full of numbers, cannot

He had to say to the two female teachers, "I hope you can use numbers or mathematical formulas to show your degree of love for me ."
  
A said, "compared with B, I love you one hundred times ."
  
B said, "A's feelings for you are certainly not as deep as my feelings for you. In comparison with a, I love you one thousand times ."
  
After listening to their affectionate words, I wonder why the math teacher s said in a gloomy manner, "isn't that equal to saying that you two don't love me at all ?"
  
What exactly is this?
  
Answer: assuming a's love is X, then B's is X/100 and 1000 * x = x/100.
X = 0
Is that simple?

★A train leaves Los Angeles at a rate of 15 miles per hour, heading for New York. Another train leaves New York at a speed of 20 miles per hour, heading for Los Angeles.

If a bird that flies 25 miles per hour leaves Los Angeles at the same time and travels between two trains, how far did the bird fly when the two trains met?

I have never been to the United States. I don't know how far Los Angeles is from New York. I assume it's X miles.

It takes X/15 hours for a 15-mile train to complete the entire process.
It takes X/20 hours for a 20-mile train to complete the entire process.
Assume that you meet each other in N hours:

15 * n + 20 * n = x/35
Flying 25 miles of birds: 25 * n = 5x/7

Is 5/7 multiplied by the total length

★Suppose the clock reaches 12 o'clock. Note that the hour and minute hands overlap. How many times does the hour and minute hands overlap in a day? Do you know the specific time when they overlap?

?

The vertices overlap.

★Two odd numbers separated by one digit are called odd pairs, such as 17 and 19. It is proved that the numbers between odd pairs can always be divided by 6 (assuming that both odd numbers are greater than 6 ).

). It is now proved that there are no odd pairs composed of three odd numbers.

The two odd numbers separated by one digit are called odd-number pairs. For example, 17 and 19 are the odd-number pairs composed of two numbers to prove that there are no three odd-number pairs.

★Suppose you have eight balls, one of which is slightly heavier, but the only way to find the ball is to place the two balls on the balance for comparison. How many times can this problem be found?

A heavier ball?

Do not renew your subscription

★Suppose you stand in front of the mirror, raise your left hand, raise your right hand, and look at yourself in the mirror. When you raise your left hand, it seems that you are raising your right hand in the mirror. But when you look up

In the mirror, rather than looking down. Why does the image in the mirror seem to be upside down, but not upside down?

The principle of the mirror is that the image is symmetric and the mirror is the axis of symmetry.

★You have 4 bottles of medicine. The weight of each pill is fixed, but one of the bottles is contaminated, the weight of the pill changes, and each pill adds a little weight.

. How did you suddenly determine which bottle of medicine was contaminated?

Use eye view or balance

★If you have a bucket of 5 kau and a bucket of 3 kau, how can you accurately produce 4 kau?

Fill in 5, fill in 3, fill in 3, and fill the remaining with another
Repeat once

★No multiplication or addition is required to increase by 8 times. Now we use the same method to increase the number by seven times.
Quality or volume

★If you have a clock that many parts can be disassembled, you can split it into blocks, but you don't remember how to split it. Then you assemble the parts again,

Finally, we found that three important parts were not put in. How do you re-assemble the clock?

 

Now I know how to install it.

5. How many stones are there?

When four children saw a rock rolling down the hillside, they began to talk about it.

"I think this rock is 17 kilograms heavy," said the first child.

"I said it had 26 kilograms," the second child disagreed.

"I think it weighs 21 kilograms," said the third child.

"You're all wrong. I think the correct weight is 20 kilograms," said the fourth child.

The four of them were so red-faced that no one would accept them. Finally, they called the stone and no one guessed the result. One of them guessed the weight and the stone's

The correct weight is 2 kg different, and the other two guessed the same weight as the correct weight of the stone. Of course, the difference mentioned here does not take positive and negative numbers into account and takes the absolute value. Please

How many stones are there?

Answer: 23

6. Three weights are called things.

There are three types of standard weights: 1g, 3G, and 9G. How many different pieces of weight can be called? What is called and known during weighing

Advanced mathematics knowledge:
7

7. Meters

There is a weight of 9 kilograms and 50 grams and 200 grams respectively. How can I weigh only three times on a daily basis and claim 2 kilograms of meters?

It is estimated that a container is not needed in half.
First 250 Second 500 third 250
Use a container to copy

The brain is not easy to use now

First 250 Second 500 third 1000
Now the weight is exactly 2 kg, but it is disappointing to let people say it again.

A is a student soldier. The smallest is a singer. If a soldier is a singer, each person is smaller than him.
C must be a soldier.

5. MIT students

Students at the University of Massachusetts come from different countries.

David, Billy, and Ted are three students: French, Japanese, and American. Currently known:

1. David does not like noodles, and Ted does not like hamburgers;

2. Noodle lovers are not French ;------

3. Japanese like hamburgers; --------------- Ted is not Japanese

4. Billy is not an American.

Which countries are these three students from?

Assuming Ted is an American, the defender may be French Billy or Japanese.
It seems that there is no problem. If David is a Japanese, Billy is French.

Therefore, this question should have one more word or one less word.

In the banquet hall of a hotel, four friends sat around and talked with each other. They use four languages: Chinese, English, French, and Japanese. Currently known:

A. Party A, Party B, and Party C can speak only one language;

B. There is a language in which three out of four will speak;

C. Jia can speak Japanese, ding can not speak Japanese, and B can't speak English;

D. A and C, C, and D cannot talk directly, and B and C can talk directly;

E. No one can speak either Japanese or French.

Excuse me, what languages does a/B/c Support?

B. there is a language in which three out of four will speak. --- D knows that the language is not A, B, and C, but a, B, and D, and C knows that the language is not Japanese,

English and e-knowledge are definitely not French. Ding must be Chinese, and Jia can speak Japanese-that is, the devil. He can speak Chinese, and B can only understand French and Chinese.

Now, there is a piece of C left. The poor British won't be able to speak Chinese, so they won't be able to discuss it with everyone! But he communicates with French, which French do not speak English.

He has learned French.

7. Take the opportunity to make a fortune

In the past, there were two neighboring countries, A and B. They had a good relationship. They not only had frequent trade exchanges with each other, but the currency was universal and the exchange rate was the same. That is to say, Country

100 yuan equals 100 yuan of B's country. However, the relationship between the two countries broke down due to an incident. Although the trade continued, the kings of the two countries declared each other's currency.

100 yuan can only be exchanged for 90 yuan of domestic currency. There was a wise man who had only 100 yuan in money from country A, but he took the opportunity to make a fortune. Please think

How did this smart person make a fortune?

In country A, he exchanged 90 yuan from country A for 100 of country B, and then to country B for 90 yuan from country B and then to country A for 100. In this way, this person holds, the more currencies the two countries change
