I applied online. The process took 3 months. I interviewed at CNN in Aug 2015
Interview
I applied online on their website. They like to get a head start on those applications. I then heard from them a couple months later for a video interview. The video interview had a recording of a HR representative. You would then respond to that representative's question while recording yourself on your computer. Be sure to look directly into the webcam. They will then give you a phone interview.
Interview questions [1]
Question 1
What has been your most difficult challenge and how did you overcome it?
it was a Hirevue, they asked typical interview questions like introduce yourself, what challenges have you faced, what's your news diet, etc. took only around 15 minutes to complete but I would do significant preparation.
Very thorough and detailed. There were three rounds of interview, and one of them was online. Then it came to in person interview. I struggled with the online because you have to record yourself and answer their questions with time limits.
I was instructed to undergo a virtual interview on Hireview. I have not heard back yet, but they asked basic questions like "tell us about yourself" and "why are you interested in this internship?"
