During this time, she also made her Berlin debut in 1902, toured with the Pospischil-Ensemble led by tragic heroine Maria Pospischil in 1906, appeared at the Vienna Burgtheater in 1907, and in 1908 at the Meinhard-Bernauer-Bühnen.

Serda was most successful for playing the naive and sentimental heroine, for example with the title role in Franz Grillparzer's tragedy The Jewess of Toledo, as Oscar Wilde's Salome, or as a cricket in Johannisfeuer by Hermann Sudermann.

She appeared as Austrian Empress Maria Theresa in Fridericus Rex (1922), and acted as Madame de Maintenon in Nanon (1924), opposite Ágnes Esterházy and Harry Liedtke.

Serda successfully made the transition to sound films, and between 1930 and 1944 she acted in over 50 productions, including Maskerade (1934), La Habanera (1937), and The Great Love (1942).

After World War II she ran a private drama studio in Dresden, only occasionally appearing on stage as part of guest performances.
