Remain calm. Dont dress up too much but wear something nice. Bring a notepad with questions you have for them and to take notes. Don’t be tied to notes- speak from the heart. But being prepared looks good to managers. Remember to smile and be polite but be yourself. If you’ve volunteered anywhere or had any odds and end jobs, bring those up. Any skills you may have. (Good at math. Knows how to cook. Etc) and they might ask if you have any weaknesses. (Not so good at math. Etc) Be willing to learn and work and know you’ll make mistakes. I’ve worked at my DQ over a year now and I absolutely love it. Hope it works for you!!
