It depends what hours you are trying to count. In the office? Remote? Actually 'working'? Including shuttle time? In my FAANG circle, small N, none of those values would be above 40 hours a week, except possibly if you include shuttle time. Certainly not anything approaching an average of 60-65 hours a week. That's averaging a 12-13 hour day, in a 10am-4pm core hour culture.
