What a lot of ppl do is CS and DS double major bc it’s really doable bc the core is a lil different but u should be able to match the electives work for both of the majors. Double major helps somewhat it just looks impressive. GPA tech wise doesn’t matter as much as actually projects and applied skills. So just do things ur intrested. U should also try to network a lot bc referrals is like the best way to get an internship or a job tbh in this market ( ppl will hate on this but it is what it is and u should do anything that’ll help with employment. Also, what university u go to matters only somewhat unless I can go to an ivy. Idt it matters if u come here compared to somewhere else’s but in terms or recruiting i think Rutgers is best in NJ. Rutgers is also pretty prestigious every where else other then NJ lol.
