I remember getting a test, in an interview in the 1990s, where I was asked to design a set of gates (ICs) to do some binary maths (Division, multiplication, etc). The input was an 8-bit set of leads, and the output was an 8-bit set of leads.

I looked at the formula, and drew two wires, connecting a couple of the leads from the input, to the output.

I was offered the job, but ended up declining it.
