1. Phone call - HR ~ 1hr 2. Phone call - Technical ~ 2hrs 3. Writing some codes for 3 days - 72hrs 4. Another technical interview - Leetcode, Big O, Algorithm, etc. It was a very very long process, took about 2 months but I got the rejection email today. Please note that this interview is difficult and time consuming and I do believe with the same amount of time and effort you can apply for better tech companies here in Dublin, e.g. Google, Facebook, Amazon, Workday. While the HR part was really good and friendly, when I was talking to tech guys I got a feeling that they are not sure what they want. They asked many Big O questions, algorithms, graphs and searches. Same as the process with Google or Facebook. I would say, if you want to work for a good company there are many better choices with a better recruitment process.

The interview process begins with a screening by the Riot Games recruiter, and then a series of 2 interviews, one personality screening with the team's producer and a second technical interview with a programmer on the team. The technical interview is preceded by a programming test which was a fairly simple task, and in the technical interview we discussed various topics relevant to Riot Games products at a high level. After the initial test and set of 2 interviews, I was invited to an additional panel of 5 interviews, with a subsequent programming assignment of higher complexity. In this second set of panel interviews, there were 2 technical interviews which were very friendly, low-stress and positive. There were also 3 personality-focused interviews, with the interviewer reading from a series of pre-prepared questions and then having me answer them.
