Saliva- If your worried about pot it's only in your mouth MAX 12 hours. Just brush teeth before interview and eat a mint or chew gum and you passed. You dont even have to chew gum or mint really if it's past 12 hours. If it is anything besides pot it will take 1 day to 2 weeks depending on the drug.
