Have you been a part of designing a survey, focus group, or performing interviews?

I would focus on the types of research you use and when you use them. There are so many options when it comes to designing research, so it's important to share not only what experience you have but the reasons why you would use one type over the other.

Avoid going too in-depth as to why you would use each. You have a limited time and you don't want to make it seem like you are giving an educational monologue on research.

"I have done all three but have the most experience in performing one-on-one interviews. They have been the most effective based on the type of clients I have worked with in the past. I do have experience in small focus groups and in designing surveys for a large audience."
