Candidate report, summarized by Dataford

I walked into a process that took almost a month, running from February 18 through March 16.

The rounds covered a lot of ground: I had a coding round focused on an Aggregated Bootstrapper API, then a system design interview about a food review system built around DoorDash orders, where reviews with over a certain thumbs-up threshold earned credit bonuses.

Debugging was tied to a Dasher Map problem where the issues came from a misconfigured hashmap initialization and null pointer errors—fixing them required careful attention to runtime failures, not just getting the logic right. The last piece of the loop was an AI coding round where I built a workflow engine for delayed deliveries.
