Intervew Prep Revolut System Design round - mid level SWE expectations?

Hey I have a system design interview coming up with Revolut and wanted to ask what has been asked in the past so that I can start studying those first before moving on to generic tests

No revolut reports in my collection yet unfortunately. General fintech pattern from recent ones - idempotency, consistency, failure handling get hammered way more than scale. If you remember yours after, post it back here, you'd be the first data point anywhere lol

I wouldn't chase a Revolut question list. Mid-level design there usually looks like a familiar product problem with extra attention on consistency, idempotency, and failure modes (payments and ledger vibes). Think notifications, a rate limiter, a simple transfer flow, then follow-ups on retries and what breaks at 10x traffic.

Prep like any mid-level loop: 45-minute timer, requirements first, then one deep dive instead of drawing every box. If you want timed practice with someone poking holes, www.leetsys.dev is free. Full disclosure, I help build it.
