Got a phone call to check personal info about graduation and visa condition. Then was told to have a interview at their office. Started with a group work test and some IQ test

Interview for South Africa graduate program. 2 rounds of interviews. First round was with HR people. Very generic interview to find out about myself, my studies, grades, interests etc. The second and final round was with the Director of carrier Department. He asked which department l would like to join, and the relevant courses that l did in university.
