I applied through university. The process took 3 weeks. I interviewed at Live Nation Entertainment (New York, NY) in Aug 2014
Interview
The interview process was very straight-forward. Applicants would send their Resume/Cover Letter and wait for a contact, then set up an interview. The interview would be 1-on-1 with the director of Live Nation New York (quite a disconcerting fact I wasn't prepared for, to interview with somebody so high-up in the company)
Interview questions [1]
Question 1
The most difficult question was regarding their flagship venues in NYC, things such as capacity, location and type of acts that usually perform on each of them. They also, rightfully, expected you to have knowledge of a myriad of upcoming concerts.
