I have my first interview with the hiring manager. It was supposed to be 30 min but he asked me for 1 hour since he had not reviewed my resume yet, so it took him a while to review and ask me some questions, regarding my current job. Then, he introduced the application that his team is working on. Then, he would like to see if I can understand the code that he wrote on the whiteboard. I could not expect technical questions in this round so I could not refresh on the technical knowledge that I wanted (I already asked the recruiter about the format when scheduling the interview but he did not respond to that). Overall, the interview was friendly and nice. We had a good conversation but I could not make it to the second round.
