There should be 2 different interviews from 2 people.

The purpose of the informational interview is to encourage you to gather more information about the particular profession you are pursuing by interviewing a professional in the field. It is also a good idea to interview a few individual members of the particular professional association or organization you are pursuing. It is an opportunity to approach a professional in order to ask specific questions about such things as skills needed to enter a field, educational requirements of a given profession, or the types of responsibilities that describe a given job classification. It is also a valuable networking opportunity.
