Candidates might struggle with anxiety about competing against a large number of qualified aspirants, leading to feelings of overwhelm. Additionally, the pressure to meet high expectations can hinder focus and motivation. Acknowledging these barriers and actively working to build a positive mindset is crucial. Support from peers, mentors, or mental health professionals can help aspirants develop coping strategies to overcome these challenges.
