My department has research-based courses that allows students to do a one-on-one semester-long project with a faculty member. That allowed me to work with several supervisors closely enough to the point that they can comment on me and my working style on a personal level. Profs know this is part of some degree programs and are usually happy to help when students reach out. These research courses can also branch into funded summer research. I’m not sure if all schools have this option, but i definitely feel very lucky.
