Difficult Negative United States

After applying, I got an OA fairly quickly and it ended up being the hardest gate in the whole process. The OA took a lot of effort and time, and it felt like a strong filter for top-tier candidates rather than a casual check. I remember walking away from it feeling that success required a very polished set of fundamentals.

One thing that stayed in my head was that the expectations weren’t just backend or just algorithmic. There was a split across areas that included both frontend and backend coding, which caught me off guard because I’d naturally be more confident in one side than the other. I didn’t end up passing, and overall the experience felt less like “try it and see” and more like “only very prepared people make it through.”

Difficult Negative Chicago, IL

Before I even talked to anyone at the company, I was asked to complete a massive 3-hour assessment with two questions. The task was framed as something required ahead of interviews, and it ended up feeling like a poor use of time relative to the work the role would actually involve.

One question was to recreate a game like Minesweeper in React. The other question covered patterns and paradigms that felt largely irrelevant to the software engineering work I’d expect to do there. I only managed to complete one of the two problems within the time limit. I didn’t get an offer, and what I remember most was how much the process front-loaded time cost without any real collaboration or adjustment once I got stuck.
