When companies hire, do they weigh where you got your graduate degree from more than your undergrad? It’s for computer science. Or will companies pay for me to get my master’s degree once I graduate from undergrad?
It depends on the position and employer.
School name is not that important, and a master’s degree in a computer field will always outrank a bachelors degree regardless of where the bachelors came from. It’s very common for a company to pay for an employee to go to graduate school part time, but that really depends on the company.
I agree with @coolguy40. For CS the school name is not all that important. Also, the schools that have very good CS programs are not always the same as the schools that are famous and highly ranked overall. For example I see MIT graduates and UMass Amherst graduates working together all the time, and no one cares who got their degree where (both have very good CS programs).
Most of the people who I know who got a master’s in CS did so because their bachelor’s was from a university in India, and they wanted to have a US degree before working in the US.
