Simon turned 20 last November, and has not featured at the 2024 IHF Women’s Junior World Championship, having already made the step towards Hungary’s senior squad. What transpired last year is that the All-Star centre back of the 2022 IHF Women’s Youth World Championship has fulfilled her potential.

At the Paris 2024 Olympic Games, where she was one of the youngest players in the competition, Simon scored 16 goals until Hungary were eliminated in the quarter-finals, also helping her side to win the match against Brazil, where she was the top scorer, with a buzzer-beater. Simon was also named the Best Young Player at the EHF EURO 2024, where she secured her first medal in senior competitions, clinching the bronze with Hungary.
