I believe they are all telling the truth, and the third one shows pictures inside the Google NYC office, though they will be broke at their salary levels and spending shown in those videos. $167 per day is $61k per year in post tax dollars, not including rent, utilities and other things. A recent grad at Goldman Sachs, a “consultant” at a big consulting firm, and a recruiter at Google (what you thought she was a programmer? She talked about recruiting two people who followed her (on TikTok/Twitter?) to a diversity program) do not make enough much money to support their lifestyles.
Using levels.fyi as a source (pretty accurate for jobs I have firsthand knowledge of):
Investment Bank Analyst at GS pays $145k and a Recruiter at Google pays $133k. After taxes, rent, student loans, and the aforementioned spending they have no money left over.
Both of those companies have large portions of their compensation as stock or bonuses. These people in the video are literally spending more than their salary on daily life and relying on getting a good bonus or their company’s stock doing well to not go bankrupt. If they got promoted they’d make more money, but I’m sure their spending would rise to match. This is what “living paycheck to paycheck” looks like for a lot of people.
