Answer:
Non-directive
Step-by-step explanation:
Non-directive interview is a totally free interview that does not specify the questions or the required answers. It is also called exploratory interview, informal or unstructured. This is an interview whose sequence and orientation is at the discretion of each interviewer, who walks within the line of least resistance or the length of subjects, without worrying about the sequence or script, but the level of depth that the interview can catch up. It is a technique criticized for its low consistency due to the fact that it is not based on a previously established itinerary or itinerary.
According to the wording and the line Anthony's questions led, we can say that he was conducting a non-directive interview.
