How would you describe what a robot is to someone who doesn't work in this field?

Some candidates become frustrated when interviewers continue to ask similar questions or questions about the same topic. This is a mistake. As a candidate, you have no idea what questions the interviewer will ask or what topics are important to their organization. A good rule of thumb is to remain calm and answer any question you are asked directly and to the best of your ability. This will ensure that you address topics important to the interviewer appropriately.

"A robot is any machine or device which can be programmed to perform a specific task. It can do complex tasks automatically, repetitively, and with more precision and efficiency than a human performing the same task. Robots can be directed either by a specific program or by reacting to external inputs or environmental conditions. Robots can mimic and appear to have human characteristics or be designed as a machine for specific functions."
