Multistage interview with a recruiter, then a discussion with the team, and then a coding challenge. After the entire process and successfully completing the coding challenge, I received a rejection. I was called again several months later. I spoke at length with the recruiter, and then I was ghosted after the conversation.

They asked about general cloud knowledge and networking, and then requested a novel coding challenge be completed. They were willing to allow any language, but the interviewer was only able to provide feedback on a couple.
