My first contact was very straightforward and mostly about getting a sense of me. The early conversations were friendly and relaxed, and I didn’t feel pressured into overly detailed questions right away. After an HR-style call, I had an online discussion with the hiring manager that lasted about an hour, and the tone felt flexible and general—more focused on understanding my personality and how I presented myself than on catching me on tricky technical points.

From there, the process moved toward deeper conversations with the team. I also had to do a presentation step where I talked through a recent project or issue for roughly twenty to thirty minutes, followed by multiple 30-minute interviews with engineers. The whole thing dragged on longer than I expected; I was told to wait for a decision after a couple weeks, but the recruiter kept following up for an answer that wouldn’t come. Eventually, I got a notice that they planned to pursue other candidates.
