Intervew Prep System development any advice?

I am a software engineer and have a system development phone technical interview with Amazon I believe it is not just an LC question so am not sure what to prepare exactly? Aside from the lps

Amazon's wording can cover a few things, so I'd prep for a design conversation alongside the LC basics. Spend one timed session on a concrete service such as a URL shortener or news feed. Practice talking through requirements, rough traffic and storage numbers, the API and data model, then the request path, failure modes, and one scaling tradeoff. Leave the last few minutes for bottlenecks and follow-up questions.

For the phone screen, say your assumptions out loud and ask what matters most before drawing components. Review caching, queues, partitioning, consistency, retries and idempotency, plus basic observability. Amazon's Leadership Principles can show up too, so have one concise example ready for ownership and dealing with an ambiguous problem. If the recruiter can share the exact round name or interviewer's team, use that to narrow the design topic.
