Sophomore Finance Internship

I applied in October and recieved an email for a first round interview before thanksgiving. The first interview was a 30 minute interview that consisted of a few behavior questions and "technical" questions that all related to American express. The technical questions were really to judge whether you researched the company or not. Behavioral Queations: Tell me about yourself/walk me through your resume, what do you think is your biggest success story? When is time you failed within a team? Technical Questions: How does American Express make money? If a business partner told you they want to roll out a credit card exclusively for college students how would you advise them?
