In 2008, Pascu won the silver medal both in the individual and the team events of the Junior European Championships in Ghent. She also earned silver at the 2011 Summer Universiade in Shenzhen, after being defeated in the final by Ukraine's Olha Kharlan. In the World Championships at Catania that same year, she had to forfeit her bout against Germany's Stefanie Kubissa in the table of 64 after she ruptured her knee ligament.
