HR called me to talk about some basic stuff and set up the interview dates. Then I had my first technical round with a Director in early Feb 2025. It had one easy DSA question and a basic scaling question. A week later, I had my 2nd technical round with a Team Lead and a Developer. The next week was the 3rd interview round with the Hiring Manager. After that, no word.
