You will not hear anything until Q'link want you to start the next stage. This could be soon or never. You will not be told how competitive you are.
Here is the email I got from QL about the traineeship. (bolding has been added by me).
All applications must be updated by close of business Thursday 19th June for the review to take place. Any changes after this date will not be reflected in the new testing schedule.
It will be communicated if you are competitive or not. This process will give everyone a clearer understand of where they stand in the recruitment process.
