Posted Apr 2025 · Candidate report, summarized by Dataford

For a senior SWE loop in Plano, the process started with a 70-minute four-question CodeSignal OA.

After that, I moved into a four-round Zoom Power Day with multiple distinct prompt types. The rounds included OOP-focused coding where I had to implement transaction functions and handle follow-ups around things like top-k, plus a systems design round centered on designing a banking app.

I also had a technical case that focused on testing cost versus budget, and it included debugging in the mix. Then there were three behavioral questions. I didn’t end up with an offer, but the experience felt like a very complete end-to-end loop with concrete prompts at every step.
