Atlanta, GAPosted Feb 2026 · Candidate report, summarized by Dataford

My process started with a coding test that went really well, and then I met the hiring manager.

In that conversation, he asked more about my experience and then shifted into rapid-fire questions about time complexities, plus when to use NoSQL versus SQL at a practical, use-case level. He also asked about Kafka use cases at a high level.

After that, I had another round with the manager’s skip leader. We spent most of the time on my project work, including where I used gRPC. I also talked through drawbacks of REST compared with gRPC. Toward the end, he asked me some C++ topics and had me implement deep copy and shallow copy constructors. I felt like he was generally satisfied.
