First round was HR which was very informal where I got to know more about the position and organization and HR enquired about my prior expereince. Second round was with the entire team with whom I am supposed to work.

Conversational interviews that last 3-45 minutes. STAR Questions asking behavioral questions. I had 3 interviews that were spaced out over 5 months. It was a LONG process and there was very little interaction with HR during this time period. I sent an email and they followed up a month later.
