Talk about a time when your communication skills greatly benefited a team effort.

"As you can see from my resume, I'm an active volunteer firefighter and communication is something that is always stressed in this field. This is especially necessary on the scene of an active fire or an accident. Last year, we were working a brush fire in conditions that were less than ideal. There were extremely high winds and our main goal was to keep the fire away from a few homes in the area. Our chief took the lead in giving orders to the team onsite and I listened and got to work. As I noticed my end getting more out of control with the wind, I didn't hesitate to get on the radio to request more help and it came quickly. I knew that controlling the far end toward the homes was vital and we were able to redirect the burning with three more men. I'm confident that the communication skills I've developed in this role will aid me in this job as a water treatment operator."

You likely can think of several different times when you used communication on the job when a team performed well. Your interviewer won't be focused on the total makeup of the team you are discussing or even what the task was. What's important here is highlighting your ability to be open with your colleagues, your prioritization of communicating things clearly, and your ability to listen and take direction when needed. If possible, make sure the scenario you discuss highlights your ability to do all of these things.
