I applied online. The process took 2 months. I interviewed at Cartoon Network in Nov 2017
Interview
After applying online by sending in my resume and cover letter thru Turner, I got the online Hirevue interview email. You do a recorded video answering questions and it comes with animates gifs! It takes about 45 min to an hr to answer all the questions, and you get about 30 seconds to 1 min to prepare for each question. There's 1 or 2 retakes per question so in case you mess up, you can record yourself again.
