worst interview ever

I went in for an interview at the discovery finance branch in waterkloof. They said to be there at 8 till 12 for my interniew. It seemed a bit long but i did not think wrong of it. Upon entering renatha took me to the back and told me that i can take a seat and start to phone people while i wait for thee person who was to interview mew which i then heard was in a meeting from 9 untill 11. So i thought to myself why do tou schedule an interview if you know the person is going to wait hours for you while in the meantime having to call a bunch of random numbers that they what looked like got from a database so i thought to myself this is the most unprofessional interview that i have ever attended a they did not ask my anything they just wanted me to call for hours on end untill one day the interview finally started. So i dicided to get up and leave after calling around 20 numbers. This all just seemed unorganised and unprofessional and in the meaanwhile there i was doing have a days work for free. I will never have a positive outlook on discovery again and will tell everyone that would consider working for them what had happened to me.
