I reached out to their lead recruiter Rob via email, who had me schedule a time to chat. The next time on his calendar was ~2 weeks away. When we chatted, I told him about my background and interests, which he responded to very positively and said I sounded like a good fit.
A couple days later, another recruiter emailed me that they wouldn't be moving forward. No idea what happened, but it sounds like the interview would be a very long process, so maybe it was a good thing.
