In particular, she recalled a recent press junket she did, as compared to her husband Ben Affleck's experience doing press for David Fincher's Gone Girl.
"We got home at night and we compared notes," she explained. "And I told him every single person who interviewed me, I mean every single one... asked me, 'How do you balance work and family?' And he said the only thing that people asked him repeatedly was about the tits on the Blurred Lines girl [model Emily Ratajkowski, his co-star in Gone Girl]."
She goes on, "As for work-life balance, he said no one asked him about it that day. As a matter of fact, no one had ever asked him about it. And we do share the same family. Isn't it time to kinda change that conversation?"
She also found it "a little bit sad" that there had to be an event celebrating women at all.
"The 'men in Hollywood' event is every day -- it's called Hollywood," she deadpanned. "Fifty-one per cent of the population should not have to schedule a special event to celebrate the fact that in an art that tells the story of what it means to be human and alive, we get to play a part."
But in an interview earlier this month with Elle, Garner did admit that her career ambitions have changed since marrying Affleck and having three children together -- Violet, 8, Seraphina, 5, and son Samuel, 2.
"My ambition shifted when I had kids in a way that I didn't anticipate," the Juno actress said. "I became more ambitious for my life as a whole, and for that kind of health and happiness of the overall family unit. And that very much includes my husband and very much includes me."
In fact, it's actually Affleck who's the one encouraging her to work more.
"My husband is always the one saying to me, 'You have to work, you have to work. This is part of who you are. We'll figure it out,'" she reveals. "That's powerful, when your partner has that serious mantra."
ET was at the star-studded Elle Women in Hollywood event in Beverly Hills, Calif., where Garner's Alexander and the Terrible, Horrible, No Good, Very Bad Day co-star Steve Carell revealed her guilty pleasure.
