I applied online and then an HR person reached out with a call. After that, I did a video call with a director about my technical skills. The director conversation felt like it went well, which made the outcome feel confusing.

A week later, HR told me they were no longer considering me. I asked for feedback after realizing I hadn’t received any follow-up, because I wanted to understand what didn’t land and what I could improve. I never heard back, and that lack of closure left a bad impression.
