PepsiCo interview questions

On Campus interview followed by on-site interview in Plano TX. All interviewers were friendly and conversational. About 45 mins - 1 hr each. Most questions were behavioral, "describe a time when you..."

I applied online through Indeed.com not even a hour later i received an email that said they wanted to interview me. then it told me to set up a interview time and i went in the interview it was very normal he explained the position and the pay (15.05) and since the shift was considered overnight there would be a .50 incentive so ($15.55) the position is part time 36 hours a week you work four days a week and the shift is from 5 pm to 3 am and after he explained the duties and etc he asked a few basic questions like Why do you want to work for this company? What do you expect from us ? Name a time you had to deal with a unsatisfied customer how did you handle the situation and what was the outcome? After the interview i asked what is the next step in the hiring process? he told me i applied through another company so they will get back with me in a week or so and he said that they categorize your application into three parts Selected, pulled and NOT selected. if your selected or pulled then you will have to submit to a drug test a physical ability test and criminal background check. Does anyone know what the Physical Test consist of or how your graded? or how to prepare?
