I received a call from the Hiring Manager for an interview. There were a total of four interviews, all telephonic, conducted by different people from different locations.

The first interview was behavioral, led by the Hiring Manager. Most of the questions focused on my previous experience, particularly the work I had done and the projects I had worked on. Then, there were some questions related to my academic projects and research work, which were general and descriptive rather than specific. Finally, there were a few questions about why I was interested in this company.

The second interview was with three senior members; I believe two were senior engineers and one interviewer was at the director level. They primarily grilled me on my projects and asked specific questions about C++ and OpenGL programming. They also asked what projects I would be interested in working on at the company if given a choice, which I believe was an important part of the interview.

The third interview was conducted by a junior engineer and a lead. The questions were related to vector calculations, graphics, and basic C++ programming.

The final interview again involved questions about vectors, followed by some tricky questions about my previous work projects, asking how I achieved certain results (e.g., "How did you actually improve performance for games – driver tweaks, etc.?").

I was then offered a 6-month internship position.

No difficult questions, but expect grilling on previous work projects and academic projects or research work you are doing at university.
