Had a 5-10 minute phone interview first before being invited to interview in-person. Did 2-3 more interviews with different managers where they asked about why I wanted to work there, etc.

Had a short phone screening and team interview, and it went well. BUT They rejected me because they don't sponsor the h1-b visa at this moment. The recruiter D was complaining to me that I didn't explain the visa situation. I was so uncomfortable proceeding with the interview process.
