I applied in mid-November 2015 and my first interview was today, which was over the phone. Lasted about 25 minutes.
The recruiter was super friendly, seemed interested in me, my answers and was relaxed.
It became clear, early on, that I was not the best candidate for this position as Riot would prefer someone with LOADS of professional experience, especially in logistics. If you're a Line Producer, or have experience at a television/news station, then you'd be a great fit. Also, they prefer someone who is an AVID gamer, primarily LOL, which also makes sense as this is a player-focused company.
While I don't anticipate getting a call-back, though, that would be amazing, I am pleased with the way things went. If I was playing LOL for at least a couple years, and had Line Producer experience, then I'd probably be moving on to the next round.
I have nothing negative to report.
