Finding out you spend all day in meetings still tells you something, especially with a few follow-up questions. Who do you spend your time meeting with? What about? How many people are typically involved? How long do meetings last?
(That said, most of the people I've been interviewed by were devs, so this was not really ever an issue.)
Yeah, when I say I spend a lot of my day in meetings, I usually get a blank look, but it's an opportunity to riff and expand on what the environment is like at the company. For example, part of my job is to protect engineer's time. One reason I go to meetings to report status and collect relevant information to condense and pass on to the team.
