had the idea of the block diagram too, will definitely go over it again so ...
that practical stuff was in the phase one written test (precisely what you said, resistor colour codes, naming componants, there was a transistor question with a TTL and FET transistor where you had to name each leg and transistor type, diode question where you had to ID the anode and cathode and a mis-wired plug)
not that I'm complaining, would be handy if this stuff came up again, but does it come up in the interview ?
been to a couple of technical interviews the last while, still get nervous but I think I have ironed out the majority of the basic point losers like you said,
for some reason though you can never get rid of interview squeeky bum time though lol
