Sorry to hear. I have never worked for Google or any corporation of that scale but I got my fair share of a harsh layoff two years ago (at a reasonably small company). The company used to run a hybrid shift, with specific days for remote and onsite. We got a mail (from the higher ups) a day before saying no employee should show up at the office the next day, under the guise of a fumigation exercise. The next day shows up, I am in a meeting with my colleagues (a regular standup), a fraction of my teammates receive an email with an meeting invite link. We join the meeting, our mics and cameras were automatically turned off by the host/organizer, the CEO's face spotlit in the meeting, he then delivered the news in a very cold way, the meeting ended, we were logged out of all company accounts in the next 15 minutes, that was the last team meeting we had :)
