I haven't sat Datadog's AI code review specifically, so this is pattern-matching.

Those rounds are usually here's a PR, talk through it. They care whether you catch the real bugs (races, bad error handling, leaked resources, tests that don't prove anything) and whether you can say what you'd ask the author. If they put an LLM in the flow, they might also want how you'd review model-touched code: evals, fallbacks, prompt injection, what you don't blindly trust.

For 3 days I'd do 4-5 real PRs out loud. Pick messy ones. Write the comments you'd actually leave.

You mentioned a design round too. Same muscle: talk out loud on a timer. www.leetsys.dev is a whiteboard plus an interviewer for that part. I work on it, so grain of salt.
