I applied online. The process took 3 weeks. I interviewed at Riot Games (Hong Kong) in Mar 2016
Interview
I got the interview 2 weeks after the submission of my resume. It was tough, energetic and you have no chance to make mistakes. They prefer experienced people so I did not get in the second round. According to my experience, you need to be loud and confident.
Interview questions [1]
Question 1
What would you do if you don't work at Riot? I said "becoming an entrepreneur", they seem to be happy about the answer.
