Explain Statistical Process Control (SPC) to me.
The interviewer is testing your basic industry knowledge. The better you understand a topic, the more clearly you should be able to answer a question like this. Keep your answer concise. 'I don't know' is never an appropriate answer. Be transparent with the interviewer that you are unsure of the solution but offer any piece of knowledge that you may have.
"SPC is an industry-wide standard for measuring and controlling quality during the manufacturing process. Statistical models are developed to use as a control, and then products are developed and monitored over a set course of time. The newly developed products are compared to the control statistics, and then variances are identified and analyzed. The value of this process is that it helps to reduce waste and helps to ensure the development that adheres to the proper specifications."
"I am not confident in my understanding of the exact purpose of SPC. However, I believe it may be a way of controlling industry standards. I would love to learn more if you would give me the opportunity."
Remember to include a brief description of why SPC is used in manufacturing. It is important to demonstrate an understanding of the value a conceptual model is intended to offer in a business setting. Intel values candidates who can make this connection.
