Here are some typical Google job interview questions from Business Insider for Product Manager, Software Engineer and Engineering Manager. The questions below are listed by category. You can find the answers at the end of the posts at here.
Product Manager:
1. How many golf balls can fit in a school bus?
2. How much should you charge to wash all the windows in Seattle?
3. 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?
4. How many piano tuners are there in the entire world?
6. Design an evacuation plan for San Francisco
7. How many times a day does a clock's hands overlap?
12. 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? (I had this interview question, not from Google.)
13. You are given 2 eggs. You have access to a 100-story building. Eggs can be very hard or very fragile means it may break if dropped from the first floor or may not even break if dropped from 100th floor. Both eggs are identical. You need to figure out the highest floor of a 100-story building an egg can be dropped without breaking. The question is how many drops you need to make. You are allowed to break 2 eggs in the process.
14. Explain a database in three sentences to your eight-year-old nephew.
15. 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?
Software Engineer:
5. Why are manhole covers round? (copied from Microsoft?)
8. Explain the significance of "dead beef".
9. A man pushed his car to a hotel and lost his fortune. What happened?
10. You need to check that your friend, Bob, has your correct phone number, but you cannot ask him directly. You must write the question on a card which and give it to Eve who will take the card to Bob and return the answer to you. What must you write on the card, besides the question, to ensure Bob can encode the message so that Eve cannot read your phone number?
Engineering Manager:
11. You're the captain of a pirate ship, and your crew gets to vote on how the gold is divided up. If fewer than half of the pirates agree with you, you die. How do you recommend apportioning the gold in such a way that you get a good share of the booty, but still survive?
...Yeah, nobody said it would be easy to get a job at Google.

US Exports To China By State
This is a great picture from Visual Economics.
Note that it says "Waste and Scrap = $7.6B between 2000 and 2008", and that's lots of "crap" been sold!

催泪歌神杨宗纬
再听一遍杨宗纬的<<听说爱情回来过>>, 还是觉得很喜欢, 很感动, 很释怀, 一首歌唱得台上台下有情人纷纷落泪...超赞!
转抄一些YouTube的留言如下:
不管聽幾次 都還是很感人 哭哭
超 "正"....生命的歌者.....
楊宗緯
听回去，感觉依然还是喜欢宗纬的歌声，还是会动容，虽然很久没他 的消息。。。 我永远支持你：）被楊宗緯的歌聲感動到不行
他後來的訪問 說到:是她..是她甩我..
那個害羞又憨傻的樣子...太好笑了
怎麼會有這麼可愛的人再聽一次還是非常回味
這是一首好歌
林版唱出女生的心聲
楊唱出男生的心聲讓人感到愛情不只回來過
它還深深的烙印在你的心中 ~~
聽楊宗緯的 "聽說愛情回來過"
這個版本每次聽都讓人感動
不去被八卦媒體左右觀點不去被有心人是惡意誤導
仔細聽他看他認識他之後
他就是一個認真又負責的人
挺~~~~
