While most technical interview challenges focus on data structures, your interviewer may ask for a general example of one of these object-oriented principles. It's important to be prepared to talk about them. The first object-oriented principle we'll be looking at is abstraction. In software development, we use abstraction to hide implementation complexity. This complexity could be in the form of an API, design, or system, and the goal of abstraction is to generalize the features of a given system. If a software product uses abstraction, it should be able to provide a user with example input, output, and a broad description of what the system does, without going into the…
