Stumbled upon a collection of Microsoft interview questions. Microsoft’s interview process is renown for being difficult and challenging, so it’s interesting to see what they’ve asked in the past. In addition to the usual riddles, algorithms, and application questions, there’s a “thinker” section. Excerpts:

• How would you explain how to use Microsoft Excel to your grandma?
• You have been assigned to design Bill Gates bathroom. Naturally, cost is not a consideration. You may not speak to Bill.
• Interviewer hands you a black pen and says nothing but “This pen is red.”
• Why is it that when you turn on the hot water in any hotel, for example, the hot water comes pouring out almost instantaneously?

The main interviewing page covers broader topics relating to interviewing…interesting stuff.
