Well its just a little interview to see if you guys actually qualify for the job based on your degree and they will also want to cross check information you provided on the website to know if it is true.
For those who were called, i congratulate them because i was informed by close sources that the cut-off mark was raised too high in order to sift the wheat.
I will not state the cut-off mark but i will wish all those who got text msg lots of luck
