This is not how to understand this. They may have been hiring for say 50 positions.
They will just fill up those 50 positions with the people who reach a threshold, not stack-rank _everyone_ who reaches the threshold and pick the top 50.
There's little ROI in doing that, and potentially it reduces their list of candidates by taking longer.
You might have been mid way through the test just as person 50 was offered their role.
