She is the 2020 Summer Olympics silver medalist and 2015 European Junior Champion. Her personal best of 71.40 m, set in 2021, is the Polish record as well as the third best result in the history of the women's javelin throw competition.
Andrejczyk represented Poland at the 2016 Summer Olympics in Rio de Janeiro. On 16 August 2016, she achieved her personal best and a new Polish national record – 67.11 metres – while competing in the qualifying round. She went on to finish fourth in the final, missing out on a bronze medal by just two centimetres.
Soon after the Olympics she underwent an operation on the injured shoulder and lost the entire 2017 season. She returned to competition in June 2018 but could not build a good enough form for the 2018 European Championships in Berlin. The next season marked an improvement as she finished second at the 2019 European Team Championships Super League held on home soil in Bydgoszcz and qualified for the 2019 World Championships in Doha, where, however, she was eliminated in the qualifying round.
