First interview on-campus at college lasted about 45 min and was guaranteed the job. Second on-site interview was merely a formality and received a job offer immediately before leaving. The interview process lasts all day and is allocated for one candidate the entire day. Back-to-back interviews lasted from 8AM to 4:30PM. Interviewed with senior members of the parent company, senior members of the subsidiary processing company I would be working for, and then had exit interviews with senior members from a sister company.
An easy high school math exam was required (algebra and geometry). Employees you might be working with took you out to lunch who did not have any part in the interview process.
