The following is a Microsoft employee in the interview the problems encountered. Microsoft consultants sometimes get some special treatment, so ask their questions when the interview does not really count, so there is no listed below.
these issues tend to follow the following basic topics: problem, computing, application, mind.
problem
★ Why sewer covers are round?
★ How many American cars? (Similar to a common question is: how many U.S. gas stations?)
★ How many manhole covers United States?
★ You make some of the people you work for seven days, you use a gold bar as a reward. This is to be divided into seven gold bars. You have to live every day to them one after the finish. If you can only cut these gold bars twice, how do you point to these workers?
★ a train to 15 miles per hour speed to leave Los Angeles, marching toward New York. Another train to 20 miles per hour speed to leave New York, marching toward the Los Angeles. If an hour while birds fly 25 miles away Los Angeles, in the round-trip flight between the two trains, I ask when two trains meet, how far the bird?
★ Assuming a disc on the turntable so as player rotation. This dish is half black, half white. Suppose you have unlimited number of color sensors. To determine the direction of disc rotation, you need to put it around the number of color sensor? They should be placed in what position?
★ Assuming the clock to 12 points. Note that the hour and minute hands overlap. In the day, hour and minute hands overlap a total of how many times? You know when they overlap the specific time?
★ You have two jars, each filled with 50 red and 50 blue glass ball glass ball. Free to pick up a jar, and then a glass ball from the inside out. How to add yourself to maximize the opportunity to get the red ball? In this way, get the red ball are the odds?
★ middle separated by only one of two odd numbers is called an odd pair, such as 17 and 19. That the total number of odd pairs can be divisible by 6 (assuming both have an odd number greater than 6). Now that is not formed by the three odd-odd pair.
★ a room with a door (the door is closed) and three light. There are 3 switches outside the house were connected with the three lamp. You can manipulate these switches, but once you open the door, you can not change the switch. Each switch control to determine which specific lamp.
★ Suppose you have eight balls,radii 420 top gold, one slightly heavier, but the only way to find the ball is to compare two balls on the scale. At least that many times to find the heavier ball?
★ Suppose you stood before the mirror, lifted his left hand, raised his right hand, look in the mirror. When you lift the left hand, the mirror seems to lift his right hand. But when you looked up when the mirror is also upward, not down. Why is the mirror image appears to reverse left and right, but not upside down?
★ You have 4 bottle of medicine. The weight of each piece pills is fixed, but a bottle of medicine which has been contaminated pills weight changes, added a bit of weight each pills. How do you measure once bottle of medicine which is contaminated it?
★ following a split-playing games, all the letters in the order have been disrupted. You have to determine what is the word. Assuming this to be apart of the five-letter word:
1. Total number of possible combinations?
2. If we know which 5 letters, then what happens?
3. Find a solution to this problem.
★ four women to cross a bridge. They are standing on one side of the bridge, let them all in 17 minutes through the bridge. Then the evening. They have only one flashlight. So two people can only cross the bridge. No matter who cross the bridge, whether a person or two people have to bring flashlights. Torch must be passed around, can not throw the past. Each woman crossing the bridge at different speeds, two speeds must be slower that the speed of the individual bridge.
first woman: Bridge takes 1 minute;
second woman: Bridge 2 minutes;
third woman: the bridge 5 minutes;
fourth woman: before Bridge 10 minutes.
For example, if the first woman and the first four women first cross the bridge, so they are past, gone for 10 minutes. If the first four women to the flashlight to send back, then waited for her to reach the other end of the bridge, spent a total of 20 minutes, the action will fail. How to make these four women cross the bridge in 17 minutes? There any way else?

You scoop a cup from the blue paint bucket, pour red paint bucket, paint bucket to scoop from the red into the blue glass paint bucket. Two barrels in which the proportion of red and blue pigments higher? By way of arithmetic to prove it.
