The "g" key is pressed That's nice, but you forgot to explain how electrical circuits work. Which ideally would have begun with with a rigorous statement of Kirchhoff's laws (and in particular how these are generalizations of Ohm's law, and corollaries of Maxwell's equations in the low-frequency limit). We were also hoping to see you demonstrate at least a basic understanding of how modern semiconductors work, to a point where we could feel confident that you were at least reasonably conversant in the underlying language of solid state physics. If you really wanted to get our attention, you would have asked for extra time at the whiteboard to derive at least, say, the 1-soliton solution to the wave equation, and used the first few terms of the expansion series to obtain both elementary conserved quantities and additional non-trivial quantities using the invariance and multiplier approach based on the well-known result that the Euler-Lagrange operator annihilates to total divergence. That is, you could have. But you didn't. We thank you for taking the time to discuss this opportunity with us; but mind you, when we said we were looking for candidates with "strong CS fundamentals", we meant it. So unfortunately we'll be moving forward with other candidates, and we wish you the best of luck with your job search.
