Hithium Energy Storage Technology interview questions

The first and second rounds with HR and hiring managers were normal interviews with normal people and questions. The third round with the direction was a complete waste of time. “ give you nails and wires, make me an inverter” “grab pen and paper please do this math problem” the entire one hour was fully dedicated to questions like above. Absolutely insult and waste of time if you have experience in the industry and given engineering educational background . It’s a joke.
