Consultants face questions like these too....

An article with the headline "Want a job at Google? Try these brainteasers first" forgets that management consulting for years has been the place for challenging interviews. A major component of the top firms' interview process is a series of case interviews, in which you go through a business situation. Variants include brainteasers and guesstimates, the type of which Google apparently uses.

The companies are trying to figure out how you think, and see your logical thought process. Anyway here are the questions from the Google interviews, the type of question of which could easily come up in consulting interviews.

How many golf balls can fit in a school bus?

About 500,000, assuming the bus is 50 balls high, 50 balls wide, and 200 balls long

You're shrunk and trapped in a blender that will turn on in 60 seconds. What do you do?

Some options:

1. Use the measurement marks to climb out

2. Try to unscrew the glass

3. Risk riding out the air current

How much should you charge to wash all the windows in Seattle?

Assuming 10,000 city blocks, 600 windows per block, five minutes per window, and a rate of $20 per hour, about $10 million

If you're going to go through interviews at the management consulting cos, I recommend practicing, a lot! I used the Vault Guide to Case Interviews and the Wet Feet Guide, though personally I preferred the WetFeet guide.
