There are three components. A take-home technical test worth a couple hours of work for 2 tasks. This test is one of the most practical and applicable tests I have seen while interviewing. The test requires knowledge of Unity best practice, 3D game dev maths, and performance considerations. An interview with the lead developer and the CTO where some basic questions surrounding knowledge of the technology stack, past experience, and how you feel about hybrid working. At this point there is also a technical talk where you can discuss the decisions you made on the technical test and how they may change given different requirements. An interview with the managing director about your goals, what you want from the company, a little bit about the hybrid working situation etc. Mostly here for culture fit but also where salary can be discussed.
