Google hiring back laid-off employees?

For very selective roles I guess. I saw another post as well in US but seems only 1 out of 50 gets a chance to be rehired.

I like the idea of rehiring, but the way this guy has shared on Linkedin is just plain stupid. "if you're good at your job you'll get noticed", as if the laid off people were underperformers. Cheap attempt to gain likes.

Shitty work ethics stop making google into a huge thing it isnt

If this is true, they will guilt you into working long hours.
Never go back to the company that fired you. If you have to, your priority should be to find a job asap
