I wouldn't recommend leetcode unless you are set on tech-first companies, entertainment co's generally aren't concerned except for the fact poor hiring practice has partially permeated broader industry tech culture. Better would be to study CS, IT, project-management, or job/industry-specific tasks you'd like to target. PBS crash-course computer science is a great way to soak some up in a jiffy.
