I was told there were no technical questions, but was in fact asked three. Ohms law, high/low frequency of household electric current (but was asked incorrectly), and frequency of home electric. Only the Ohms law could possibly apply to the job - but not for anyone starting. The two managers actually argued about the correct answer in front of me, one did not understand the Ohm's law question, and another manager was confused by the AC current wave high/low question.
