Hi Dimensions,
You won't receive any feedback apart from either an email asking you to book a time for a phone interview (if successful), or a thanks for coming, try again in 12 months email if you were unsuccessful. At least you are feeling good after the online testing, I thought I completely stuffed it when I completed the testing a few months ago. But here I am, now at the referee check stage
All the best with your application, this thread has a wealth of information, be sure to use it
