I liked to test the boundaries of what was okay to talk about and I understood that others did not think it was particularly feminine to question and be outspoken.It was also during high school that Janouch decided to become a journalist, of which she had a "romantic image".

After university studies in art science and literature (she did not get into the journalist education she wanted), she became a translator at a book publisher, and got to work as a proofreader at Expressen.

According to Expressen,[14] Expo,[15] and Aktuelltfokus,[16] Janouch has sometimes expressed controversial views on Sweden's "irresponsible migration policy"[17] due to reports of increasing crimes[18][19][20][21][22] and political correctness.

[26] In March 2017, Janouch began as a columnist at the far right Sweden Democrats-affiliated political newspaper Nyheter Idag[27] She wrote: "Because I'm allergic to all kinds of extremism, both right and left, I want to write on a fresh independent platform".

[30] In December 2018 Voice of Europe published an article about Janouch's participation in the protest against the Social Democrats signing the Global Compact contract and she said "do not mess with the sons and daughters of the Vikings".

[32] During a debate hosted by the far right media platform Swebbtv, Katerina Janouch was invited to comment on the "low intense war being committed in Sweden".

[33] In an article by WJLA published in March 2018 about the increase of sex crimes and violence against women, Katerina Janouch was quoted saying "Sweden has changed very much.

"[34] Since 2018, Janouch has become active in right wing movements with closer ties to white supremacy and conspiracy theories, such as the network Education4Future where she was a founding member.
