Given that your name is "uberemployee"... and that your comment history shows you are for lack of a better term an uber jingoist, I have to ask...
How do I know you're not some HR shill trying to do damage control?
/I say this half jokingly
Obviously it isn't. You don't choose the city you grow up in, and you have a limited choice over the school you go to. Football team is perhaps the closest in your list - if you support a team that has repeatedly cheated to win games then perhaps it's not unreasonable to judge a person based on their loyalty to that team.
To be clear, I'm not actually that convinced in the argument to not hire Uber employees based on their employment record. But we should at least represent the argument correctly.
My cohort of friends, many of whom are hiring managers, won’t even patronize Uber, much less hire someone who voluntarily worked there without demonstrably showing signs of serious soul searching about the ethics of the company.
3,000 engineers is not particularly out of line. It's certainly not ludicrous. It's a very large, global business, that is likely to get a lot bigger yet.
Still nothing to scoff at.
I’m extremely proud of the work I’ve done at Uber. I have no worries about finding my next job. I have a laundry list of companies who have contacted me since Jan 1, 2018, including FANG.
If the company doesn’t want to hire me because of where I work, I’m happy to not work for anyone who makes snap judgements based on resume line items. That’s basically like excluding people because of the city they grew up in, the school they went to, or the football teams that they support. I’m happy never working for or alongside people like that.
