There was an initial phone screen with the recruiter. Then, I had an interview with the hiring manager. From there, I was given a take-home submitted anonymously. Once the take-home was assessed I was scheduled for a panel interview that took about 3 hours, over two days with 3 different people. Two from my team and one cross-functional.

This was the best interview process I've ever experienced. The recruiter is always in communication. DO is the only company I've seen deliver their rejections by phone, and the conversation is very transparent but kind--they highlight the positive feedback, but at the same you aren't left wondering why you were rejected (in my case, I didn't do well enough on the technical, as I had suspected). While other companies may ghost or send a generic rejection email, DO will go the extra mile to speak with you. Definitely apply here if you're interested. The only downside I want to mention is that it sounds like they get a lot of applicants (+1000 for the position I applied for), so you will likely face some strong competition.
