The questions you ask in a UX research interview will depend on the specific goals and objectives of your research project. However, there are some general principles you can follow to ensure that your questions are effective.

First, your questions should be focused on understanding the experiences and perceptions of your interviewees. What are their thoughts and feelings about the topic at hand? How do they use the product or service in question? What are their pain points and needs?

Second, your questions should be open-ended and avoid leading the respondent. Avoid yes/no questions and instead ask questions that encourage the interviewee to share their thoughts and feelings in detail.

Third, you should avoid asking questions that can be easily looked up online. Instead, focus on questions that will help you understand the interviewee's personal experiences and opinions.

Finally, remember to listen carefully to the responses to your questions and follow up with probing questions as needed. The goal is to understand the interviewee's perspective, so be sure to ask clarifying questions if necessary.
