Riot Games Software Engineer interview questions

I applied for the job online, and got a email from a recruiter on Saturday night, asking me to book a time slot for a phone call. The email looked like auto-generated, but I booked a time slot anyway. I also replied to that email to confirm the time I booked. Got no response. On the designated time, the recruiter did call me, the chat was very short, about 15 minutes, mainly about when can I start, what kind of project am I interested in etc., and of course briefly asked about my recent project. I thought the chat went pretty well, it was friendly and nice communication. One thing that I was surprised about is that for the very first question he asked how often do I play LoL. I answered with honesty that I am a long time Dota player and only tried LoL last weekend and liked it. After the phone call I sent the recruiter a brief thank you letter. No response. Two days later I got a standard auto-generated rejection letter, not from the recruiter but from the online system. I can't say it's a good experience. The recruiter seemed to be in a rush and never answered emails, got rejected without a technical phone screen, no explanation about the rejection from the recruiter. To this date I still don't know what went wrong. Anyway, it's an unusual experience for me. For software engineer roles, I either get silently rejected or start with a technical phone screen, HR phone calls are normally just for data collection, but maybe I was wrong, they do screen people through HR phone calls first.

They call you and ask you questions based on your experience and education. They then ask you why you want to work at Riot. Their interview questions also involve some logic puzzles to get to know how your brain works.
