If possible, find out who you'll be reporting to and do research on this person to get a sense of their interests and what their personality might be like. You should choose a professional who shares common ground with your supervisor.

Either way, choose an professional whose work you've studied or followed and highlight the reasons that you respect and admire them. Speak on the qualities of the work, especially any qualities that are relevant to the aspirations of the publication or your superior.

The key here is that who you're talking about shares common ground in some way with the publication or the people you'll be working with.
