Imaging science. If I were hiring another imaging scientist:

Write your own Fourier Transform. [If your FizzBuzz questions involve actually writing/coding the FizzBuzz, I'd not request actually writing it...]

I wonder how effective of a test this would be. Are the algorithmic & implementation details of the Fourier transform that important to imaging science? I would imagine that explaining the properties of the FT, it's connection to imaging modalities, etc would be far more relevant than actually coding a DFT.

How would you weight a naive implementation of the DFT vs the FFT?

Luckily he didn't specify the dimensional requirements, so we can get away with f^[0] = f[0].
