Chicago, ILPosted Sep 2025 · Candidate report, summarized by Dataford

My interview started with a coding round that felt like Linked List work—something in the “LC easy or solid medium” range depending on how you interpret it.

It wasn’t the hardest part, but it was still focused and fairly specific, and it set the stage for what came next.

The second round was system design, and that’s where things got genuinely difficult. The bar felt higher than I expected, and I remember struggling more to structure the explanation and go deep enough. It wasn’t just a quick high-level conversation; it demanded a lot of clarity and breadth. I ended up not getting an offer, and the biggest takeaway from the process was realizing how much more demanding that system design round was compared to the initial coding screen.
