Graham the Plumbers' Merchant interview questions

Very basic interview. Interviewer said "I cant make the job out to be anything it is not. i just need someone to free up my time so i can do what i need to do" Didn't ask any questions about my experience, only asked my age and if I still lived at home. I WAS offered the job originally and when I called back to find out what ID and such they needed (as requested) and the interviewer (who is also the same person who offered me the job) said "Sorry Bab, we must have told the wrong person" Not to mention the fact my mobile number was blocked and I could only get through when i rang off someone else's phone. Absolute joke.
