Pop earned a silver medal at the 2008 Junior World Championships in Acireale, then at the 2009 Summer Universiade in Belgrade. She was briefly selected into the national team during the injury of team captain Ana Maria Brânză, then served as reserve upon Brânză's return. She became Romania's number 2 in the reshuffling that followed the 2012 Summer Olympics and the retirement of Simona Gherman, Anca Măroiu, and Loredana Dinu. She also transferred to CSA Steaua București, of which national team colleagues Brânză and Maria Udrea are also members.
