Interview tips

Everything else in this course is about the vocabulary - objects, relationships, principles, patterns. This module is about the forty-five minutes where you have to perform with that vocabulary in front of someone who is grading you: how to run an OOD interview, how the machine coding variant changes the deal, how to turn a paragraph of requirements into entities and relationships, how "clean" quietly redefines itself under a clock, how to pick a pattern instead of hunting for an excuse to use one, and what an interviewer actually wants to hear when the design has shared mutable state.
