The Chore Experts interview questions

Called within a couple of days after I sent application. Office for interview was a small, unorganized, dirty, an I just felt like it wasnt a business setting. Unprofessional when their phones kept ringing. Its a husband/wife owned vusiness. Initially saw ad for job opening online where it said like $12 an hr. Up to like $400/wk. But then i found out at interview its not actually hourly its by compensation. So they were never clear how much id get paid but assured me "none of their employees ever complained". At end of interview was told Id be called back that wk no matter what the decision was if they were gonna hire me or not. But....no one ever called.
