The earliest stage started with recruiter coordination that came with clear expectations. I had conversations where the recruiter strongly suggested doing LeetCode-style practice because the upcoming work would match that pattern, and the tone made it seem like the technical part would be predictable. Then, when I got to the next technical touchpoint, the exercise didn’t align cleanly with what the recruiter had prepared me for. I was left wondering whether the mismatch was intentional or just a breakdown in what the team needed.

In another attempt with Hopper, the recruiter process also moved slowly enough that it felt like I was being kept warm while the company was already making decisions. When I finally reached the assessment stage, I did remote interviews across multiple sessions focused heavily on programming and data structures, with an additional behavioral conversation near the end. The overall difficulty was high enough that it didn’t feel like a quick screening—it felt like a serious time commitment, even though the structure stayed mostly “technical, technical, technical, then behavior.”
