My Approach To Coding Interviews: Optimize For Iteration

tl;dr: “I didn’t encounter this question in an interview personally. I’ll be pretending to go through a ~60 minute interview with an imaginary interviewer. And what you will read here is how I would tackle this question and how I predict the interview would go, informed by my experience in interviews. While reading all of this, it’s important to remember that the most important part of an interview is communication. Keep your interviewer in the loop! Not only tell them what you are currently doing, but also what you are working towards. Think out loud and describe what your ideas are and how you plan to implement them. Most interviewers want to help and will reinforce good ideas and try and prevent you from going down the wrong path. A coder that can’t articulate what they are doing is likely not going to do well in a team environment.”
