As a game engineer I can relate. Many of these deep technical areas are completely unknown to people outside of gaming / modeling / animation / graphics, and even then you are way outside my expertise with optical/pre-digital work. It is a great point that interviewers focused on typescript or redux (just to mention stuff worth knowing but that seem far from C++ graphics coding) won’t get the nuance of your technical contributions. It then becomes a storytelling challenge, which is a different interviewing skill entirely.
