For some time he worked as chaplain in Krajné (then Krajna) and in Bratislava (then Pozsony), but then left preaching and started working as a literary critic, journalist, poet, historian, theoretician, and organizer of Slovak cultural and awareness activities. From 1918 to 1919 Krčméry edited Národné noviny, worked as the editor-in-chief of Slovenské pohľady, and acted as secretary to the reinstated Matica slovenská. From 1920 to 1921 Krčméry undertook a studying trip to Paris together with his wife Hela. Upon his return, he again worked as the secretary of Matica slovenská and was the editor of the renewed Slovenské pohľady (1922–1932), Knižnica Slovenských pohľadov, and temporarily also Slovenský ochotník, Naše divadlo, Včielka and other magazines. In 1930 he left for 3 months to Prague, where he took additional courses at the Charles University, and received a PhD.
