they are wasting time

My brother has been called for an interview on Sunday, the interview was supposed to be held on Monday. Only to find out this company is in Gauteng. They reschedule the interview on Thursday. Then I did little research about this company, I found out they are wasting people's time, actually that information was revealed by \HelloPeter site\". I decided to phone them asking them few questions, what is the post for job interview, and what exactly they do? The guy answered the phone didn't respond on my questions, he just dropped the phone on me. If it was genuine company, they don't have to hide anything. This job interview was advertised on Career 24. The number for this company is cellphone number: ***."
