That was good Ken, but why not sit on the unfinished chair, conduct the interview, while you put it together, and then announce how you always multi-task, plus it shows you are handy and can “fix” any situation.

just the clock problem of microsoft

it comes to the modulo 12 calculation

12 t = t ( modulo 12)
11 t = 0

t = 12 k /11 for k=0,1,2,3,4,5,6,7,8,9,10

since solution of t is in modulo 12 it makes no sence to have a k >= 11

the interval is
12/11*5 minutes = 5.454545 minutes

which is : 5 ‘ 27 ” 27/100

1.How many golf balls can fit in a school bus?
Are they inflate?

2.Imagine a disk spinning like a record player turn table. Half of the disk is black and the other is white. Assume you have an unlimited number of color sensors. How many sensors would you have to place around the disk to determine the direction the disk is spinning? Where would they be placed?
See Feynman lectures on physics.

3.a) 24
b) 11

Questions by Google
1. How many golf balls can fit in a school bus?
Twice as many as the number of golf balls that it takes to fill half the space in a school bus.
2. You are shrunk to the height of a nickel and your mass is proportionally reduced so as to maintain your original density. You are then thrown into an empty glass blender. The blades will start moving in 60 seconds. What do you do?
Sit on the blade at its center point, and then hold on tight.
3. How many piano tuners are there in the entire world?
The number of pianos in the world divided by x.
4. In a country in which people only want boys, every family continues to have children until they have a boy. If they have a girl, they have another child. If they have a boy, they stop. What is the proportion of boys to girls in the country?
This scenario has no bearing on the answer. With any pregnancy, there is a 50/50 chance of having a boy or a girl. (You can have 9 families, where 8 have boys with the first pregnancy and the ninth has 1 girl then 1 boy. The ratio would be 9 boys to 1 girl. You can have 1 family that has 9 girls then a boy. That ratio would be 9 girls to 1 boy.)
5. Describe a chicken using a programming language.
main () {
printf (“A chicken is a tasty bird that produces tasty eggs.”);
}
Questions by Microsoft
1. You have a bucket of jelly beans. Some are red, some are blue, and some green. With your eyes closed, pick out 2 of a like color. How many do you have to grab to be sure you have 2 of the same?
Four. (The number of colors in the bucket plus 1.)
2. Pairs of primes separated by a single number are called prime pairs. Examples are 17 and 19. Prove that the number between a prime pair is always divisible by 6 (assuming both numbers in the pair are greater than 6). Now prove that there are no ‘prime triples.’
Because all primes are odd numbers, with the exception of 2, and sequential integers always alternate between odd and even numbers, then the number between prime pairs must be even, thus divisible evenly by 2. One in every three sequential integers is divisible by 3. Because of this, the number between the 2 primes must be the one divisible by 3. If the number between the prime pair is always divisible by 2 and by 6, then it must also be divisible by 2×3, i.e. 6.
3. Imagine an analog clock set to 12 o’clock. Note that the hour and minute hands overlap. How many times each day do both the hour and minute hands overlap?
22, 11 times each full rotation of the hour hand. (As the minute hand approaches the hour hand after the eleventh hour, it finally overlaps at the twelfth hour.)
How would you determine the exact times of the day that this occurs?
With eleven overlaps every 12 hours and 60 minutes in an hour, the number of minutes after each hour that the hour and minute hands overlap is 60 divided by 11 multiplied by the number of hours after 12:00.
4. How much does a 747 weigh?
747 tons, plus or minus 747 tons.
5. Imagine a disk spinning like a record player turn table. Half of the disk is black and the other is white. Assume you have an unlimited number of color sensors. How many sensors would you have to place around the disk to determine the direction the disk is spinning?
Two.
Where would they be placed?
They can be placed anywhere, except where the line between the two sensors would cross the center point of the disk.

Typical Ikea “puzzle”; some of the screws are missing!
