The interview was conducted in a number of rounds, all in person - first HR, then line manager, followed by teammates, and couples to follow I assume (since they found a more suitable candidate afterwards). The HR already briefed that their hiring process takes quite a while cause they want to ensure both the company and the candidate is confident in joining their team, so they normally arrange not only the HR and line manager, but also other department heads or teammates that would be working closely with the position.
