Cummins Engineering Placement (Multiple Roles) interview questions

Applied for the 12-month Engineering Placement position. It was a straightforward process, leading straight to a phone interview. I was interviewed straightaway by the hiring manager, who is an engineer himself. Hence, I didn't have to worry about getting past an annoying HR stage. However, it was quite tough as he immediately started the ball running and went into the technical bits. Towards the end of the interview, then only he asked basic information about me.
