Know the two layers
There are two choices, not one. Interview type is the outer layer, picked as a card on Basic Details: Resume Screening, AI Interview, Human-Led Interview, AI Prompt Assessment, Coding Test. Round type is the inner layer, picked on Round Configuration, and it only applies when the Interview type is AI Interview. Eight round types sit inside that one card.
