Office layoffs are weird too. A friend worked for Oculus. One day they went to lunch and the manager muttered something quietly about the whole team being laid off then ran off. A team of like 10-15 people had to stand outside and wait for security to bring out their stuff. Sounds pretty awkward.

Another large company I worked for sent out random meeting with the CIO, if you got the meeting you were laid off. At least the CIO did it himself.
