I applied through university. The process took 1+ week. I interviewed at Caterpillar (Kharagpur, West Bengal) in Dec 2023
Interview
There was an online test which had general questions from various domains of mechanical engineering. Then the shortlisted candidates were interviewed asking Fluid mechanics and Heat trasfer questions which were very fundamental.
Interview questions [1]
