Microsoft Interview Question

Study your basic data structures: how to implement a few of the main ones, performance/size considerations. Practice some interview questions (e.g. leetcode) on a white board or piece of paper and practice speaking aloud. Speak about how you're approaching the problem, some pros/cons of your approach. When studying interview questions, really focus on the techniques associated with solving general problems (greedy, two pointer, etc.) as it's highly unlikely that you'll see a question you've seen before. The interview questions are designed to be novel. Prepare by knowing how to solve problems, not memorizing solutions.
