He also completed postgraduate studies in Public Law there in 2002, and received a master's degree in Private Law from the same institution in 2004. In 2001, Cseke interned at a notary public office in Marghita; from that year until the following, he worked as a reviewer at the UDMR's Bihor County chapter. From 2002 to 2005, he was a legal adviser to the President of the Bihor County Council. Cseke's political involvement began in 1997, when he joined the UDMR. From 2002 to 2003, he was president of its Bihor County chapter's commission for supervising regulations. In 2003, he became a member of the party's Union Representatives’ Council. From 2003 to 2005, he was executive vice president of the Bihor County UDMR, as well as a member of its county operative council.

In December 2009, when four ministerial portfolios were assigned to the UDMR in a cabinet led by the Democratic Liberal Party's Emil Boc, Cseke's party assigned him to the Health Ministry. The following month, he proposed a tax on fatty, salty and sugary foods, with the revenue to be used in the public health sector. He has called for reforms in Romania's health care system, including a focus on allowing family physicians to practice medicine rather than become entangled in bureaucracy, saying it risks total paralysis otherwise. He also cautioned that cuts in investment and infrastructure would be necessary as a result of the ongoing financial crisis, but said that doctors and nurses, already too few in number, would not be laid off. He resigned in August 2011, citing insufficient allocation of funds for the health system and what he indicated was a dismissive attitude toward health care by the rest of the government.

That December, he was elected for a seat in the Chamber, where he was vice president of the public administration committee.
