The entire process took one month (from when I submitted my application, to when I got the offer). The actual interview process took a couple weeks.
Overall, the interviews were very straightforward. It started with a quick 15 minute phone screening where they ask you about yourself, and some logistics (can you work in the country, are you available, etc.)
Then, I had a technical interview with two technical artists. They basically just go through your portfolio, asking questions about the projects you've done. There weren't any actual coding questions, but this gave me the chance to really explain the breadth of my knowledge.
Lastly, I had a team fit interview where I was interviewed by a project manager. This was more behavioral, and just assessed how I liked to work, if I'm more independant or work in a team, etc. All very standard stuff. I got an offer a few days later.
All of the interviews felt like a casual discussion, and it absolutely put me at ease. Definetly the most relaxing and stress free interview process I've ever done.
