I think there may be some difference in starting salaries, but not huge ones. When we were looking at colleges average salaries from RPI vs CMU were about $10,000 apart. But whether two kids from either school were getting the same exact salary, if they started in the same position at the same company I don’t know. If you do end up going to MIT or CMU for grad school - your employer will be looking at what you accomplished there. It CS, it’s all about skills and experience. Get internships wherever you end up.
IMO the schools you mentioned are at pretty much the same level. Not the tippy tippy top, but all very good.
