I freeze in interviews, tips?

I get tongue-tied when I am asked about my weaknesses. There are 16 people counting on me, so I am trying to be careful. The role is similar to my old job as a call-centre agent. What calms you down?

Arrive early, drink water and take a slow breath before you walk in. It sounds simple but it helps.

Ask about the first ninety days. It shows you are thinking about the work.
