I applied at Internships.com. The next day I received an email asking for an appointment for a phone interview. After the phone interview, I had explored other options then set up a date for a 1:1. I met with the director of the gallery, whom I had spoke with on the phone, and we discussed the daily tasks and other expectations they would have of me. In retrospect, after speaking with other interns, it seems whoever conducts the phone interview is the person you work under, and you become "their" intern or employee.
