PRC Group interview questions

It was disorganized, from the beginning there was no one to open the door, the receptionist was out for lunch. The interview itself wasn't structured properly, lasted for more than one hour. At the end they showed me around and said they are happy with me but they would prefer to sleep on their final decision over night.... and never came back again, even with final decision or feedback. Really left me in funny sense about this company. BTW their Office Manager have had a blue face (I think she lives in office and they expect someone to do the same for fairly low pay).
