Riot Games interview questions

Received an email saying that they would like to proceed my application to the first interview stage. Submitted my preferred interview slot time and emailed back saying thank you and have selected the time slot. For the next few days, did not receive an interview invitation link. On the day of the interview, followed up twice on the confirmation timing before the actual interview time. No response. Basically no interview link /instruction was being sent out. No idea what happened to the recruiter. So did not manage to get an interview.
