Don't bother with the interviews. I breezed through all the technical challenges, got to the final cultural fit interview with the CTO. I was later told I didn't have the skills they were looking for, even though the Head Architect, Head of Engineering, Head of Product, a staff engineer and the hiring manager all gave me a strong hire in the technical rounds. Waste of time, generic rejection email too. I did tell them I would be working fully remote which they were OK with, I guess they didn't think I would actually make it through the process and just wanted to waste time, then thought better of it when I got to the end.
