GS students use the same career center and online platform as other students (CC/SEAS). Only the people within Columbia really pay attention to the difference between CC/SEAS/Barnard/GS.
Outside of this bubble, not many people care. But note that when applying for jobs at some high brow firms (like IB or consulting) the first round interview will be with people who graduated from Columbia. But as long as you have a good GPA and do well on the interviews, I don’t think it makes a difference.
Note that some wall street firms specifically look for GS students. Mainly because of maturity, and military experience.
