An interview is not considered recoverable data, so no reference to this is provided in the reference list. You may, however, cite the interview within the text as a personal communication. "Use a personal communication citation only when a recoverable source is not available."
Examples of personal communication -- "emails, text messages, online chats or direct messages, personal interviews, telephone conversations, live speeches, nonarchived social media livestreams (e.g., Instagram Live, Twitter Spaces), unrecorded webinars, unrecorded classroom lectures, memos, letters, messages from nonarchived discussion groups or online bulletin boards etc."
