THE PROCESS

The point of coding questions is to try to determine how well you can code. It’s the most important part of the interview because the code you write and the answers you give to the interviewer largely determine whether you’re recommended for the job.

The Scenario

You usually work one-on-one with your interviewer. The interviewer may provide you a computer, but often will give you only a marker and a whiteboard (or pen and paper) and ask you to write some code. The interviewer usually wants you to talk through the question before you start coding. Generally, you are asked to write a function or method, but sometimes you need to write a class definition or a sequence of related code modules. In any case, you write code, either in an actual programming language or in some form of pseudocode. (The closer you can get to actual working code, the better.)

The Problems
