gpa usually past 3.5 it doesn’t do too much unless the graduate / research route. Some internship/co op programs have gpa requirements which is where passing that threshold can help. It looks good but they would want to see experience & projects you can talk about. Helps a lot for scholarships though!
at least at my school (not ivy league but top cs school), profs say they won’t bring anyone in their lab with a 4.0. really good shit but ofc it helps. it also doesn’t hurt if it falls although that might depend on school. it matters for grad school, less for companies except quant where it will. labs do not care at all
