My first step was a quick recruiter-driven call where the focus was almost entirely on my projects. I tried to give a one-sentence snapshot for each team and company so I could cover my experience efficiently, but the interviewer stopped me earlier than I expected and zoomed into one of my projects for deeper discussion.

The timing ended shortly after that, and I was declined. What bothered me was that the conversation never really went into technical depth, even though my background was meant to be reviewed on technical grounds.
