Anecdotally, I've been told they require you to come onsite to get onboarded and receive Google hardware and their offices are locked up. Some recent hires are not able to work and now being paid to do nothing.
They are mailing out the required hardware and doing remote onboarding for the time being. But hardware shipments are getting delayed leading to some new hires being paid to do nothing for a week or two.
I've heard on-boarding is totally remote now - they mail you a badge and a laptop and the laptop has the requisite forms and software pre-loaded.
