Strictly speaking, she says she did some work "on the roof in the morning" and then doesn't mention work again at any point. In particular the video gives the strong impression that she might have simply gone home soon after lunch. Maybe not in reality, but it strongly looks and sounds that way from the vid. She says explicitly "I got lunch, I got a snack always, I then shuttled home" i.e. the phrasing means going home immediately followed lunch. You also have to wonder how hard she can be working and how well supervised she is, if she's posting videos to their primary competitor of herself dancing on the roof.
There's also a more subtle issue here than the lack of work. She talks like someone whose primary interest is her own looks, not anything to do with tech. She talks repeatedly about how cute she looks, how she spends time working out to look cute, and a large part of the video is her posing in the mirror. Even something like the actual product she works on, isn't worthy of a mention. At 23 how much product management knowledge or skill can you really have, or heck any form of management skill? Traditionally, managers are meant to be people who have done the work of the people they're managing so they can make informed decisions. Given the widespread awareness that tech firms do 'diversity hiring' all the time it leads directly to the suspicion that maybe she was hired because she's a cute 23 year old girl and not, say, because of her extensive experience of product design or committed work ethic. Firms like FB used to have very strict hiring standards, but look at the employee growth in the past few years and tell us that this can still be true. Someone like that would simply never have made it through the interviews 10 years ago. They are clearly a bullshitter, look at this:

"Prior to working at Meta (priorly Facebook), I built 3 startups and I put 2 out of the 3 startups through the UCLA Summer Accelerator program. This accelerator is founded by my good friend and mentor, Robert Jadon and accelerated my growth as an entrepreneur and woman in tech."
And:

"During her senior year at UCLA, Riley Rojas decided to pursue a career in Big Tech — and she wanted to work for the best ... This week in #KeepingtheBalance, Rojas shares how she landed her job at Meta with a political science background. Spoiler: It took a whole lot of studying and manifestation."
So of course that will lead to resentment. She studied political science yet claims to have made three startups before she even graduated? The pay for these jobs is famously good. What possible value can this person be delivering to meta?
