I don't think so? My current employer has a #xoogler Slack channel, so named because that's what people will look for. You can say it's uncool if you like, but that's the word people use.

I think in the case of FAANG (or whatever the acronym is these days), if you worked for one of the big guys in the past it's worth making it obvious if you're looking for work. If not only to stand out from other applicants, also to set an expectations for higher desired salary.

Does it also bother you when people have bumper stickers of the college they went to?
