The MOST important thing for Dorji to check in preparation for recruitment season is to make sure he is not tagged in any photos or has posted any photos where he and his friends are doing something that is against school policy.
This is crucial because recruiters often look at a potential recruit's online presence as part of their evaluation process. Unprofessional or inappropriate images could negatively impact Dorji's chances of being recruited, regardless of his achievements and stats. While the other options are important, ensuring a positive digital footprint comes first.
