If you didn't get any feedback after the 2nd Online Test, odds are, its an error in delivery. It's impossible to say if you succeeded or not.
As per the interview, if the alphabetical list is anything to go by, which I personally believe it is because Gbenga Ademilowo had his interview on Monday and I know of a fellow whose surname is Z, he had his interview on Friday(in fact, his name was the last on the list).
People have been getting feedback after the friday interview to pick their preferred departments. BAT has even called some people to confirm some qualificatioon details. Odds are, the Screening/Interview has ended.
You can call AGDC to inquire and confirm if the BAT interviews are over.
You can also call BAT directly to get closure.
As the equal opportunity clause states, may the best qualified candidates win...
