What experience do you have with CAT tools? Which ones?

CAT tools are Computer Assisted Translation tools, and they are often used to support translating long texts, completing audiovisual translations, translating a series of texts with commonalities, and much more. The interviewer is interested in a candidate with experience using these tools and likely requires them in this position. When you review the job description, look for specific details on what tools are used and what level of experience is expected. If you don't have experience with CAT tools or those listed on the job description, then research the tools that are listed so you are able to reference them and speak to them in your interview; this will demonstrate a base understanding of the tools, and you can share your aptitude for learning and picking up new software quickly.
