One introductory call with the recruiter (15 min), and a panel interview with two senior managers of the studio (1 hour). The whole process was very smooth, and surprisingly there weren't any coding questions. Overall, the process and people were great. My advice: If you don't have much game dev experience, don't let the lack of experience throw you off. What's important is to show your strength and demonstrate what professional skills you can bring to the table (in my case it's C++)
