At the junior level, Kostornaia is the 2018 Junior World silver medalist, the 2018–19 Junior Grand Prix Final champion, the 2017–18 Junior Grand Prix Final silver medalist, and a two-time Russian junior national silver medalist (2018, 2019).

Kostornaia is the tenth woman in history to have landed the triple Axel jump in a senior international competition. Kostornaia is the third woman after teammate Elizaveta Tuktamysheva and Rika Kihira of Japan to attempt and land the maximum number of triple jumps allowed in one senior international competition: four in the short program and eight in the free skate (see Zayak rule). She first accomplished this at the 2019 Internationaux de France, and later landed all twelve triples cleanly at the 2019–20 Grand Prix Final.
