What experience do you have using team-based messaging applications?
There are many options for communication software and messaging applications. Give the interviewer a brief overview of the apps you are experienced in and assure them that you can learn their internal system, should it be new to you.
"I have used a variety of team-based messaging applications. I am best versed in Brosix, AOL Instant Messenger, and Freedcamp. No matter which system you use I am sure that I can pick it up very quickly."
"Although I have not worked with a team based messaging application, I am confident that I would learn very quickly. Which team based messaging apps do you use at Rubrik? I would love to get a head start and begin learning."
