I'd also like to add that one of the ways we offer a level playing field for candidates is by strongly supporting remote work (which started long before COVID-19). We have multiple offices both within and outside of the United States, and many people who work from home in jurisdictions where we have the ability to employ people. Unlike the team in the grandparent comment, many Twitter engineering teams are currently particularly looking to hire outside of San Francisco (both to increase our geographic diversity and to reach the best candidates wherever they may be).
So if you're looking for something new, like Twitter, and see a role on https://careers.twitter.com that you honestly feel is a good fit, please apply!
