I had applied through an employee and got call from directly from the director of the team. Had 3 rounds in total, the first round was in person with the director, mostly he asked about my background and projects and told me what his team does. Very casual and non technical. The next round was with my manager and an architect on the team. It was mostly on my resume asking about my past projects and internships. There was a long gap after that(almost 2 months) where I had given hope. Suddenly the architect emails me to schedule another round which I felt was weird because I remember asking on the previous round if there would be one round and they said no. This was more technical with SQL questions, it was not hard but difficult to answer since there it was all hypothetical
