Perguntas de entrevista da empresa payever

The one thing they really grilled me on was a deep dive into the architectural flaws of my technical task, specifically asking: "Why did you choose this specific state management pattern over a simpler service-based approach, and how will your solution handle race conditions if two different payment webhooks hit this endpoint at the exact same millisecond?" It wasn't just a casual conversation; they wanted me to defend every line of code I wrote under pressure. They pushed me to explain the trade-offs between system consistency and speed, forcing me to prove that I wasn't just following a tutorial but actually understood how to build a resilient, high-concurrency fintech system that won't crash when traffic spikes.

They asked me to explain how I would design and scale a backend service, including API design, data flow, and handling edge cases.
