My first step was an early technical prompt that was much broader than I expected for an initial stage. I had to build something like a high-frequency banking system from scratch, which meant thinking beyond one algorithm and covering the moving parts end to end. It was comprehensive, but once I broke the problem down, I could see a way through it.
The next round was a live interview with behavioral and coding components. The coding portion didn't match the frontend expectation I'd been given. Instead, it focused heavily on DSA and then escalated into a hard LeetCode-style challenge. The technical bar felt real, and so did the time pressure.
If I had passed that stage, the process would have continued with several longer interviews, including multiple coding rounds, system design, and meetings with product and a hiring manager. The early rounds felt like they were filtering for someone who could handle that level of depth and pace. I didn't receive an offer, but the experience made it clear how demanding the later onsite would have been.
Location: Warsaw, Masovia. Overall feedback: Positive. Offer status: No offer.
