How the interview runs

1.Clarify. Restate the problem in your own words and ask anything you'd want to know about the input.
2.Approach. What's your approach? Start with the brute force if it helps, then improve it.
3.Code. Go ahead and write it in the editor. Talk me through it as you go.
4.Test. Walk through your code with an example, including an edge case.
5.Complexity. What's the time and space complexity, and could you do better?
