My process ended up being long and segmented, with multiple technical conversations stacked back to back. I had three technical rounds, each around two hours, and the topics were broad—OOP concepts and SQL came up, along with JavaScript and Java concepts. I also got questions that pulled from my resume projects, plus puzzles, and even basic questions that touched on networking/OS, database basics, and AWS.

One day ended up being packed. I remember moving through several rounds in sequence—an initial screen that felt more like a written/presentation-style checkpoint, then a coding round, then two technical interviews, and finally an HR round. Puzzles and technical competencies from my resume were explicitly part of what they asked, and the whole thing ran multiple rounds without much downtime. What surprised me was how quickly it moved from concept checks into puzzles and deeper topic coverage. I didn’t get an offer, and the experience left me feeling like I had to be solid across a wide spread of fundamentals, not just one area.
