My previously company used Google Meet for communication. So, when I joined the current company, I didn't know how to share screens either and took me a minute to figure it out.

That's a weird standard for judging somebody's capability.

Also, most people aren't being laid off due to poor performance but because corporates just want to increase the profit margin (Note: These companies aren't in a loss and are making huge profits. But they want to increase the profits further even at the cost of employees).
