Joubert has had an up-and-down career. He has switched coaches many times. He was briefly coached by Alexei Yagudin. He is now coached by Jean-Christophe Simond. At the 2005 World Championships, he placed sixth. Nevertheless, he was seen as a threat for an Olympic medal. But at the Olympics, he placed 6th. He was criticized harshly in the French press for this. After the 2006 Worlds, where he won the silver medal, he said he felt pressured to do it in part because of the way the French press had turned on him.
