A friend of mine had an interview a couple weeks ago with Google Inc.
He provided me a list of just some of the questions he was asked. I’ve
added a few more from others I have talked to who had interviews with
the internet giant, Google, as well. See if you can answer them. Many
are open ended with several right answers, therefore I did not provide
the answers.
1. How many golf balls can fit 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?
3. How much should you charge to wash all the windows in Seattle?
4. How would you find out if a machine’s stack grows up or down in memory?
5. Explain a database in three sentences to your eight-year-old nephew.
6. How many times a day does a clock’s hands overlap?
7. You have to get from point A to point B. You don’t know if you can get there. What would you do?
8. Imagine you have a closet full of shirts. It’s
very hard to find a shirt. So what can you do to organize your shirts
for easy retrieval?
9. Every man in a village of 100 married couples
has cheated on his wife. Every wife in the village instantly knows when
a man other than her husband has cheated, but does not know when her
own husband has. The village has a law that does not allow for
adultery. Any wife who can prove that her husband is unfaithful must
kill him that very day. The women of the village would never disobey
this law. One day, the queen of the village visits and announces that
at least one husband has been unfaithful. What happens?
10. 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?
11. If the probability of observing a car in 30
minutes on a highway is 0.95, what is the probability of observing a
car in 10 minutes (assuming constant default probability)?
12. If you look at a clock and the time is 3:15,
what is the angle between the hour and the minute hands? (The answer to
this is not zero!)
13. Four people need to cross a rickety rope bridge
to get back to their camp at night. Unfortunately, they only have one
flashlight and it only has enough light left for seventeen minutes. The
bridge is too dangerous to cross without a flashlight, and it?s only
strong enough to support two people at any given time. Each of the
campers walks at a different speed. One can cross the bridge in 1
minute, another in 2 minutes, the third in 5 minutes, and the slow poke
takes 10 minutes to cross. How do the campers make it across in 17
minutes?
14. You are at a party with a friend and 10 people
are present including you and the friend. your friend makes you a wager
that for every person you find that has the same birthday as you, you
get $1; for every person he finds that does not have the same birthday
as you, he gets $2. would you accept the wager?
15. How many piano tuners are there in the entire world?
16. You have eight balls all of the same size. 7 of
them weigh the same, and one of them weighs slightly more. How can you
find the ball that is heavier by using a balance and only two weighings?
17. You have five pirates, ranked from 5 to 1 in
descending order. The top pirate has the right to propose how 100 gold
coins should be divided among them. But the others get to vote on his
plan, and if fewer than half agree with him, he gets killed. How should
he allocate the gold in order to maximize his share but live to enjoy
it? (Hint: One pirate ends up with 98 percent of the gold.)
Do you still think you have what it takes to work for Google?
