I would say it is important to know that for MBA internships, NBCUniversal places all the MBAs in one pool and the hiring managers get choose they are willing to interview. For me the interview process was informal. I was called by an executive assistant and only interviewed with two people -- both of which were behavioral interviews. I initially did not think I would receive an offer as several weeks passed before I was called back with an offer.

Started with HireVue video interview then a phone call with someone on the team. Did not get moved to the next round (which was not communicated to me by HR, I had to email the interviewer a week or so later to find out)
