PM interview - ten design questions

In response to "How would you design a kitchen?" series, few people had asked me about typical design questions. While the questions may range from designing an object like a cup to designing an ad-serving platform, here are some practice-questions.

1.       Design a web cam

2.       Design an object model and an API for a chat client

3.       Design a photo-viewer application for mobile devices

4.       Design a paint brush (physical paint brush)

5.       Design a washing machine/dryer  for clothes

6.       Design a switch for a sun roof opener in the car

7.       Design notepad (software)

8.       Design a cellphone for a retired person

9.       Design a computer for your grandma

10.   Design the $100 laptop

the list continues...
