Data scientists use various tools and methodologies to accomplish their tasks and ensure the results they produce are accurate. You should discuss these with authority during your interview for a data scientist job at Microsoft. You may have also recognized this as a technical question. This is a typical structure of a technical question - asking you to define a term and provide an example of how it is used in your profession. Your answer should address the definition first, then provide an example of how you would use this item in your job.

"Decision trees are graphical models used to illustrate the options available and the choices made during a decision process. A decision tree is intuitive and easy to build. However, it lacks accuracy, so it should only be used to illustrate the process. Like a tree, it begins with a base or trunk and then grows. Each decision option is called a node. The last decision options are at the top of the tree and are known as leaves."
