I cannot reveal the questions I got asked. But here's some that has very similar flavor: 1) Check if an integer is a palindrome (do not convert the integer to string) 2) Given 2 sorted arrays of integers, code to find a number from each array such that their sum are closest to some integer K? 3) What is the degree of freedom for lasso?

You have a function which gets k as input and in o(1) time returns a random number between 1 to k. Create a function that returns a random permutation (a list of the numbers 1 to n in a random order), optimize for speed (I think O(n) is best).
