The rankings posted above by wonder are based on research and graduate programs. You care about undergrad. Out of these, if you get directly admitted to CS for all, the best ranking would be
- UWashington
- GA Tech
- UT Austin
- UW madison and Purdue
This is not ranked with research, it’s ranked with job availability (UW has a lot of job recruiters come and fight over a very small amount of students - everyone get a job! they also have the most amount of undergraduate research awards [of all schools], but that doesn’t matter to you unless you want to do that)
