Which tech company is laying off or freeze hiring because of COVID19?

My girlfriend is a recruiter in tech and there have been no signals, yet.

i work for a non-tech megacorp ; it will not surprise me if hiring is paused if everyone switches to working from home, since the org is not set up to enable efficient working from home -- not much point hiring anyone since not much project work will be getting done, and we won't be able to onboard any new people effectively even if we did hire them.
