Likely they covered MIPS assembly at university. MIPS is a comparatively simple architecture and thus is used a lot in CS courses.

The thing here is, if they really wanted to show off that she’s got a good carreer and doing something remarkable, they could have just done what she did in her comment. List her current position and maybe her education.

I’d not be very happy if someone were to present my skills and achivements as “Can use these programming languages”.
