One thing that I would like to see from Riot is more discussion about the jobs.
Extra information on the Riot Games Careers page regarding who receives resumes, extra information about applying for internships, information regarding foreign employees, etc.
Yet another possibility, perhaps, would be is to set up something new for Riot Games that has been done for numerous other sites. Q&A with specific members in regards to their job, how they got it, what they like about it, etc.
I'm mostly bringing this up for personal reasons, as I had sent a message to Riot Games in regards to foreign interns, requirements, etc. yet, after nearly two months, I've yet to hear anything back.
I would love to intern at Riot Games and, hopefully, end up working for the company that has kept me playing a game more than anything else I've ever played. I love everything about the company, except for the few things I have pointed out. :>
