Hi Kristov
the length of time before you find out doesn't mean anything. i found out a few weeks back i was through. did my test on the Wed and found out nine days later on the Fri.
Those who were sadly unsuccessful were all told in less than a week. I think this is because if you have been successful, someone at HR needs to take the time to actually phone you (in my case anyway), whereas unsuccessful folk generally just get emailed.
hope that helps, good luck.
