Arani Power Systems Interview Questions and Answers

The hardest round I have experienced during interviews was ultimately successful, as I was selected. Only a few questions were multiple-choice; the rest required one-word or numerical answers to be written manually. Pay special attention to the last portion, as it was a scoring section containing standard technical questions. However, as we begin the assessment, the majority of the time is consumed by reasoning, arithmetic, and similar topics. In summary, I can say that the initial part is the toughest.

Q1. The interview consisted of questions related to thermodynamics, including the Rankine cycle, the laws of thermodynamics, and knowledge about boilers and boiler safety. Additionally, most questions focused ...read more
