First, I had a call with an employee in the Marketing Department in the New York Office. Just a general informational interview so I could better understand what they were looking for and they could understand what I could offer. No surprises!
Then, I had a call with a remote employee from the Marketing Department. Again, more informational so this employee could weigh in on what she thought of me.
Lastly, I had a video call (since I wasn't in NY) with the Marketing Dept. supervisor, who asked me some questions and gave me a few math problems to solve. Then I spoke again with the first woman I spoke with on the phone and she checked to see how much I knew about the company.
Got a call later that week telling me they were offering me the internship.
