Amazon Operations Engineer L5

Hey everyone, I have an Amazon Operations Engineer (L5) Loop interview coming up next week and was hoping to hear from anyone who has been through the process.
From what I have been told, the role is more focused on design implementation, vendor management, installation/commissioning, and driving safety and throughput improvements. It also sounds like it involves around 80% travel.

1. Has anyone interviewed for this role or worked on this team? I’d love to hear about:
2. What the Loop interviews were like
3. The kind of technical questions they asked
4. Which Leadership Principles came up the most
5. What the day-to-day work is actually like?
6. Whether the travel is really as frequent as advertised

Any tips, things you wish you would have known before the interview or advice on how to prepare would be hugely appreciated. Thanks!
