The interview process took almost a whole day. The company paid for airfare, hotel, car rental, and meals.

Interviewed with several different departments, including HR, administrative, industrial engineering, and business development.

A lot of academic and technical questions, but none that were too difficult. There was a trick question where there was no answer, and the interviewer walks you through a wrong answer. They want to see if you say something or let it slide. Other than that, nothing too difficult.
