Personal interviews are not included in the reference list because they are not considered recoverable data. You may cite them within the text as a personal communication.
In-text citation:
Eating too much sugar is unhealthy (J. Donahue, personal communication, April 19, 2014).

If you have read or listened to the interview (i.e they are retrievable in audio or print form), use the reference format appropriate for the source.
Unlike informational interviews, recoverable interviews from archives, multimedia, and publications are listed in both in-text citation and reference list. For interviews published online or in print, follow the appropriate guides and format for a specific reference (e.g. magazine, journal, and blog post). In some cases, you can combine different elements that correspond to a certain source to provide the readers with the essential information to locate the reference.
For interviews with no formal title, write "Interview by (Name of the Interviewer)" in lieu of the title.
