Include the name of the interviewee and the date interviewed for APA style in-text citations. You should also note that it was a personal communication. For example: (Z. Levi, personal communication, July 23, 2011). Don't cite interviews on a reference list for APA style.
Cite MLA interviews in-text with the last name of the person interviewed in parentheses. For example: (Gomez).
Cite the interview in an MLA citation with the name of the person interviewed, the phrase "personal interview" and the interview date. For example: McAvoy, James. Personal interview. 19 April 2011.
Cite published interviews in MLA style with the interviewee's name, the name of the interview, the title of the work the interview appeared in (if applicable), the author of the article and publication information. For example: Hamilton, Kate. Interview with Michael Fassbender. Empire Magazine. By Jane Smith. Boston, MA: 23-27, 2009. Print.
