Hi my name is John Cromer and I came for an interview and I would like to know what day of next week will I hear from you guys.

You should call them

Hello , you would have to call the store .

You would need to contact the person who you interview with.

Well I already had the interview I just asking a question

I can't answer that. It would be best to contact the store. Ask if you can schedule an interview. That way it makes you look more interested. Good luck John.
