I applied through an employee referral. The process took 3 weeks. I interviewed at Litton Entertainment (Burbank, CA) in Jan 2015
Interview
They call you in, ask what projects/shows you've worked on and how it relates to their current programming. They'll ask if you can handle X, Y & Z - you'll say yes and then they'll hire you for a low rate. Then have you do the job of someone several positions above you.
Interview questions [1]
Question 1
What do you want to do for a career within the industry?
