Is it OK to Pause Before Closing a Case?

Question:
Is it OK to ask for 1 minute to gather my thoughts before concluding?

My Reply:
Yes, absolutely this is okay.

Keep in mind that in an interview situation, a 1 minute pause feels like 10 minutes to the interviewee (you in this case)?

Just realize to the interviewer, it's not a big deal. We just mentally start thinking about emails to reply to, our calendar, what's for lunch, etc…

So better to pause briefly and end with a strong concise, conclusion than to rush it.
