This is an operational question that the interviewer uses to better understand how you perform your job. The best way to respond to an operational question is to break down the processes you use into individual steps and briefly describe them in the order in which you execute them. Your answer to an operational question should be brief and to the point. You should also anticipate follow-up questions.

William Swansen

"When creating a data-based decision-making system, the first thing I do is interview the users to understand the problems they are trying to solve. I then research the sources of information that are relevant to the company's operations. Once I understand these, I create a system that incorporates databases, artificial intelligence tools, and machine learning principles. The final step is to develop a user interface which enables the employees to quickly access the information they need."
