Had a 30 min chat with the CTO. Mostly, basic questions about work experience and projects. They would get back to me within 2-3 days. Never heard back from them again.

I applied through a 3rd party recruiter. First, I had a 15 min phone interview with the CTO, followed by a 3 hr onsite where I talked to managers in non-technical roles. Then I had another 3 hr onsite with just the CEO and myself where we discussed something I'd built previously.
