⚡ Why engineers lose the offer
You know the work. Explaining it under pressure is different.
Interviewers don't stop at definitions. They ask how you'd size it, why you chose it, and what you'd do when the site clashes with the drawing.

Technical RoundMEP Consultant · HVAC
LIVEInterviewerExplain the open-loop and closed-loop concepts as applied to HVAC hydronic systems.
Your answerA closed loop is sealed from the atmosphere, like a chilled-water loop, so the pump only overcomes friction. An open loop is exposed to atmosphere, like condenser water through a cooling tower, so the pump must also handle static lift.
Interview pointThey're checking whether you understand how loop type changes pump head selection and water treatment.
RememberClosed = friction only. Open = friction + static lift.
