The following is a problem that Microsoft's employees encountered during the interview. Microsoft's consultants sometimes get some special treatment, so ask their problems when interviewing is not true, so they are not listed below.
These issues often follow some of the following basic topics: problems, operations, applications, minds.
problem
★ Why is the well cover of the sewer?
★ How many cars in the United States? (A common similar problem is: How many gas stations have there be been in the United States?)
★ How many sewer holes are there in the United States?
★ You let some people have worked for seven days for you, and you have to use a gold bar as a remuneration. This gold bars are divided into seven. You must give them a piece after you have a daily life. If you can only cut this gold bars twice, how do you give these workers?
★ A train leaves Los Angeles at a speed of 15 miles per hour, and in New York. Another train leaves New York at 20 miles per hour, and in Los Angeles. If a 25 mile of birds flying per hour will leave Los Angeles, go to and from two trains, how far is the bird fly when two trains meet?
★ Assume that a disc is rotated like a player. This plate is half a black, half is white. Suppose you have some color sensors that are not limited. To determine the direction of the disc rotation, how many color sensors do you need to be around it? Where should they be placed?
★ Assume that the clock is 12 o'clock. Pay attention to the hour hand and the division overlapping together. How many times is it in a day? Do you know if they overlap?
★ You have two tins, twisting 50 red glass balls and 50 blue glass balls. I am free to pick up a jar and take out a glass ball from inside. How to maximize the opportunity to get yourself to the red ball? How much is the chance to get the red ball?
★ Two odd numbers only separated by a number are odd, such as 17 and 19. Certification odd pair between the total number of times is 6 (assuming these two odd numbers are greater than 6). It is now proved that there is no odd pair consisting of three odd numbers.
★ A house has a door (the door is closed) and 3 lights. There are 3 switches outside the house, which is connected to these 3 lights. You can manipulate these switches at will, and once you open the door, you can't change the switch. Determine which lights for each switch specific tube.
★ Suppose you have 8 balls, one of which is slightly slightly, but the only way to find this ball is to put two balls in the balance. How many times can you find this more heavy ball?
★ Suppose you stand in front of the mirror, lift your left hand, lift your right hand, look at yourself in the mirror. When you lift your left hand, you look up in your right hand. But when you look up, yourself in the mirror is on your back, not your head. Why is the image in the mirror seem to be reversed, but didn't reverse it?
★ You have 4 bottles of medicine. The weight of each pill is fixed, but a bottle of drug has been polluted, and the weight of the pill has changed, and each pill has increased weight. How do you measure which bottle drug is contaminated?
★ Play a split game below, the order of all letters is chaos. You have to judge what this word is. Assume that this watched word consists of 5 letters:
1. How many possible combination of possible combination?
2. If we know which 5 letters, what happens?
3. Find a way to solve this problem.
★ 4 women have to pass a bridge. They all stand on the bridge, let them pass this bridge within 17 minutes. That is at night. They only have one flashlight. You can only make two people over the bridge at the same time. No matter who has passed the bridge, no matter whether it is a person or two people, you must take a flashlight. The flashlight must be transmitted, and cannot throw it. Each woman has different speeds, and the speed of two people must pass the bridge at a slower person.
The first woman: It takes 1 minute to pass the bridge;
Second Woman: It takes 2 minutes by bridge;
Third Woman: It takes 5 minutes by bridge;
Fourth woman: 10 minutes of crossing the bridge.
For example, if the first woman has passed the bridge with the fourth woman, when they passed, they have passed 10 minutes. If the 4th woman will send the flashlight back, wait for her to reach the other end of the bridge, a total of 20 minutes, the action will fail. How to make these 4 women over the bridge within 17 minutes? Is there anything else?
★ If you have a 5 quart bucket and a 3 quart bucket, how to accurate 4 quart water?
★ You have a bag of sugar, with red, blue, green. Close your eyes, take out two color the same sugar, how many times you need to make sure there are two colors?
★ If you have two buckets, a red pigment is red, and the other is blue pigment. You pick a cup from the blue pigment barrel, pour in the red pigment barrel, and then pour a cup from the red pigment bucket and pour it into the blue piglet. Which is higher than the proportion of red blue pigments in the two buckets? This is proved by arithmetic way.
