People often say that the better you understand a concept, the easier it should be for you to explain in simple terms. For this reason, the interviewer may ask you questions based on the fundamentals of CNC operations.

A vernier, in short, is a measuring tool used to measure parts of your work or a workpiece.

Take your existing knowledge of a vernier and explain it in simple, easy to understand terms. Imagine that you are describing a vernier to someone outside of your industry. How could you help them to understand?

"I find that I have a knack for explaining concepts to others. I believe in the adage that if you cannot explain a concept to a Grade 5 student, then you don't understand it well enough. If I were to explain what a vernier is, in its simplest terms, I would say that it's a tool used to measure the parts that I make on the job!"
