How can a company like Twitter or AirBnb have 3900 employees or more?
I don't mean any disrespect to people at those companies and just took examples I looked up, I just can't understand what all are doing.
I see this with others too, like WeWork and Uber. Companies that are more or less one platform, employ a lot of people doing things that is not clear for the average user.
What is the % of people doing what? Like how many server admins, frontend devs or customer support persons are there ?
EDIT: So I do NOT mean "uhhhh I could do that so easy". I was just interested in what and how many people are doing what, and for example how much is mobile optimization work vs normal desktop site and how much is spent on AB testing, is there a team for that and so on.
