Got a recruiter call from a resume I dropped back in 2019. Probably as my current position is more interesting to them now.

The process involved several rounds:

• Recruiter reached out about various teams/positions. I decided to pick the Delivery team. They were working with releasing the Gitlab application stack (Rails app + DB) on Kubernetes. Plus, they are also involved with the process of packaging features from other teams into a release.
• Chat with the hiring manager.
• Technical interview (Kubernetes).
• 2x Peer Interviews (general Q&A with members of the team).
• Final interview with Director of Infra + another manager.
• Decision.

In the technical interview, I was given a Kubernetes cluster with some common problems in connectivity/scheduling, etc. The task was to figure out what was wrong.

The next couple of interviews focused on specific knowledge in releasing software (due to the team).

There wasn't a clear format, just "tell me how you release this web app + what problems do you expect."

My guess is that they are trying to see if you have done this in multiple ways.
