Write a function in Java that will take a sorted array of ints, possibly with duplicates, and compact the array removing all the duplicate numbers. That is, if the contains the numbers - 1, 3, 7, 7, 8, 9, 9, 9, 10, then when the function returns, the contents should be - 1, 3, 7, 8, 9, 10. Be sure your answer is as efficient as possible. Describe the efficiency of your algorithm using big O notation.
how would you design how a cellphone implements its contact list when you press a certain letter. For example, If you press M it will tell you all the names starting with M. then if you press MI it will tell you all names starting from MI and so forth....

Given a number n, give me a function that returns the nth fibonacci number. Running time, space complexity, iterative vs. recursive.
When was a time in your life where you received criticism and how did you react?
No tough questions were asked. They just wanted to know if I could accept it and meet their deadlines.
How do you find three numbers that sum to 0? (in a list). Now can you do it under O(n^3)?
What is the sum of the square root of every number from 1 to 100?
Swap two variables without using a temp.
The interviewer gives you 100 blank cards, and you can write a single positive integer on each card. The interviewer looks at the cards when you're done (so he knows the probability distribution of the deck), then shuffles the deck. The interviewer guesses the top card of the deck, and if he's right, he makes in $ the number written on the card. What numbers should you write on the cards to minimize the expected return of the interviewer?
