I applied online and received a response about a week later. Within another week, I had a phone screen with a recruiter, followed by an online coding challenge (two questions on Codility). The following week involved a video interview with a manager, focusing on work experience and behavioral questions. This initial process took about three weeks in total.

They scheduled me for an on-site visit about two weeks out at the office in Irvine, CA. In the meantime, the recruiters offered plenty of interviewing advice and even called a few days before to go over the schedule and what to expect. The on-site took about six hours and was broken into four 1:1 or 1:2 person interviews, a lunch break with "lunch buddies," and a recap with the lead recruiter.

The recruiting team was very polite, clear, and prompt, and the interviewers were relaxed and inviting. Visiting the Twitch OC office itself was a blast. They packed me a "goodie bag" full of snacks, gave me a tour (which featured amazing game-related art), and made sure I felt at home before diving in. The team managed to turn what would normally be an intimidating interview marathon into a fun tech conversation. Hands-down, the best recruiting experience I've ever had.

There were several questions aimed at designing around constraints (i.e., given a scalability/performance/security/etc. restriction, what tools/architecture/etc. would you use to solve a problem).
