It was a decent interviewing experience. 95% of the questions come from their script (majority of which are behavioral based) and solely tie into Riot's Values and Craft (your skill). I got in through a referral. I connected with the HM (person I would be reporting into) for an introductory call, then came a phone interview w/a Sr. Recruiter, then virtual onsite with 5 individuals (1 hour each).
Intro call - pretty standard, think of it as a recruiter call to briefly go over your background, experiences, and for you to learn more about the position.
Video Phone Interview ( 1hr) - w/a Sr. Recruiter which focused on your "craft". Across the company, your "craft" is essentially how well do you do your job. They follow a script and ask you behavioral based questions. And why Riot? Luckily they removed that prior LoL gaming knowledge requirement.
Virtual Video Onsite - w/5 individuals ranging from peers, to leaders to your HM and finally the SLI (senior leader interviewer/hiring sponsor - who gives the final decision on your candidacy). Each person will have a focus: Riot Values (A - candidate experience/thrive together), Communication/Collaboration, Critical Thinking Problem Solving, Riot Values (B - Dare to Dream, Execute with Excellence, and Stay Hungry, Stay Humble [from what I know, this is usually conducted by the SLI so you'd have to do well in this interview]), and Craft again.
Questions came from their question bank/script and required you to answer in STAR format since it's all behavioral. The last Craft Interview threw me off because a lot of the questions tested my recruiting knowledge, which TBH any recruiter can look up online and know the answer - ex: what're some OOP languages?
