My path started with a practical assignment flow. I was given a Golang-or-PHP style home task via GitHub and an Engineer-facing prompt, then later moved into an interview phase built around what I’d done. I also saw a pattern of resume review showing up before a more live design conversation tied to the assignment.

The interview I got next was an about-an-hour discussion centered on the Java work I’d submitted—what I built, and what I’d improve. Interestingly, the person leading the discussion didn’t seem deeply rooted in Java, so I had to explain my choices more carefully than I expected. Still, the overall level felt manageable for someone with experience in web development, and the questions stayed in the realm of design tradeoffs and incremental improvements.
