Addison interview questions

Interview starts with a 30 minute test which was 15 logic puzzles (?) and 5 hvac questions around 20 questions total. Hvac questions included drawing a ph diagram of the refrigeration cycle and one with subcooling and reheat, drawing a cycle on a psychrometric chart with cooling and reheat, drawing a cycle on psychrometric chart with return and supply mixing, and calculating sensible and total btu using the psychrometric chart. If you're in an AC-adjacent or not related industry memorize the equation for total btu, the equation for sensible btu, what a dcv system does and what is the benefit, the difference between vav and cav, the conversion from kW to BTUH. All of these were asked during discussion portion. Was told position was not technical during interview (?). One interviewer said he had to stop himself from asking an illegal question. Condescension. 🚩🚩🚩🚩🚩
