One thing I do to give myself time to think is to just rephrase the question as a way to ensure I understood correctly as well as demonstrating that you're listening and participating. I then ask clarifying questions and ask for them to confirm any assumptions I'm making based upon answers given as part of my thought process. It's just thinking out loud and can also help demonstrate _how_ you think about problems. This lays the groundwork for you to construct a cohesive narrative.
