Given two lists, A and B, of sizes n and k, respectively, describe an algorithm to determine the intersection, C, of the two lists. What is the complexity of your algorithm? (The obvious solution is O(n*k)). Can you describe a solution that is faster? (An optimized solution can do it in O(n+k)).

Probably the most difficult question they asked me was, he put a binary tree on the whiteboard and I had to write a function that would find if the tree was symmetrical or not. Anyone who's familiar with data structures and recursion should be fine with this, just don't freak out when they propose the question.
