After the initial short interview with the recruiter online, I got an in-person interview invitation from the PI. And then, a few weeks after the in-person interview with the PI and the lab, I got the offer.

1 virtual interview with 1 person. It was fairly laid back with basic interview questions, "about me", etc. It lasted approximately 20-25 minutes. I did not hear back any news for about 2-3 weeks, then was offered the position.
