This is a great team to consider at Twitter. But if this isn't quite what you're looking for, I'd just like to add that many teams at Twitter are specifically looking to hire people outside of San Francisco (either at other offices or working from home... but note that we don't yet have the ability to directly employ people in every country). Protip: even if a job listing mentions a location different from where you live, apply anyway and mention where you'd want to work from. We are currently actively hiring for many teams (see https://careers.twitter.com). For now, all interviews are virtual, including virtual office tours if you would intend to eventually work in one of our offices once they reopen after COVID-19 is under control. (Modulo the undeniable stress of current world events, which we all try to support each other through), the transition to 100% remote work has gone remarkably well.
I'm sorry that you or someone you know ended up not receiving an offer. Twitter is indeed still hiring. While admittedly Twitter does hold a high bar for hiring, we put a lot of effort into making sure that our assessments are done fairly, based on the best we can tell about the candidate's current level of technical and nontechnical skills relevant to the role. Sometimes this may mean teams continue the interview process further with candidates who seem promising but risky. When that does happen, it's not because of a number of applicants metric (this isn't a metric I've heard about internally), it's because we want to give people a fair chance. Admittedly, there is a careful balance to be made between giving people the time to demonstrate how they shine and wasting candidates' time because it's not the right role. There's also cases where someone interviews for one role, doesn't have the right skill set there, is referred to a different role, and then does very well and is hired. I don't think any interview process at any company is perfect, but we are always trying to improve.
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!
