Three rounds of interviews. The first two were conducted online due to COVID, but the third was in-person. The first was with the director of my department, and the second was with HR, followed by a session with a licensed psychologist who assessed my readiness for the position. If you're invited back for a third interview, it means that they want to hire you. At the third interview you are shown the kind of material you'd be dealing with on a day to day basis, and then have a debrief with a licensed counselor who is there to support you in making a decision about whether the company and job is right for you.
