So did he answer it or no?
It doesn't sound like they asked for the most efficient answer, so all he had to do was iterate the tree, find the median, then sort left and right based on the median. Voila, balanced tree. While not the most efficient approach, it will give the correct answer.
A real engineer should be able to think of trivial, inefficient answers like this.
