List for me the machinery that you are most accustomed to operating.

The interviewer would like assurance that you can handle the type of machinery that they operate at Mettler-Toledo. Talk to the interviewer about your exposure to machinery and any manufacturing specific experience that you may have. Be sure to ask the interviewer if they are looking for a particular type of machinery. This question will allow you to overcome any potential objections later. If specific machinery experience is requested in the job description, be sure to address that as well.

If you have the right experience: "I see from your job description that you are looking for experience in machines X, Y, and Z. I have run these specific pieces of equipment for the past 12 years and consider myself an expert with them. Are there any other machine operating skills that you desire?"
