The upstream comment mentioned Linear Algebra as a base requirement for applied programmers in their domain; satellites, remote sensing, communications, navigation, etc.
You can assume they're interested in esoterics like those who can grasp the spherical harmonic equations used to model the daily magnetic flux epoch models to control sats via mag torque, those who can do a multivariate 512 dimensional SVD reduction against pipelined multi spectral data to create sharpened images, create fuel optimal paths in constrained resource starved environments while dodging projected debris paths, .. you know, all that jazz.
