KFC Cook interview questions

I was so nervous at the first cuz I didn't know what to say but the interview was not I expected that hard. It was going so well and it was easy. The interviewer handed the application form to me and tell I have to work 2 shifts in weekday and minimum hour for 1 shift is 4 hours which means I need to work until 9pm. I wasn't sure if I can make it cuz I need to study tho. And she told me to ask my parents if it's okay then hand the form back if not just call her and tell her.
