You often hear about HN posters complaining that when they do go into the office, they’re just having Zoom calls in the office instead. That’s what Amazon is trying to fix here. Everyone in office 5 days a week.
Not really. At a company the size of Amazon teams are often in other buildings, if not other cities or countries entirely. The zoom calls continue unabated.
If you have 3 days of office, you'll always be in Zoom calls because at least some of the team members will be at home.
