Amazon Software Engineer internship interview questions

On campus interview, 3 coding questions. The hardest one is a knapsack problem. A list representing pages of each book A list representing intelligence you can get by reading a book A number indicating the pages you could read at most one day return the highest intelligence you can get.

Applied on their site. I was sent the test by e-mail and I had 2 hours to solve it and send back the results. It was fairly easy, questions about lists and graphs.
