Nobody is treated exactly the same as everybody else.
Companies don’t hire colleges- they hire individuals. You should make a phone appointment to talk to career services at Columbia; find out what is and is not available for GS seniors, and make a decision.
You may need more/less support than a 21 year old “traditional” senior; you may have broader or more narrow interests; you may want to be applying for fellowships or go straight to a professional career. You can’t lump all these outcomes together-- each pathway has its own twists and turns.
Talk to someone at GS Career Services and find out what is and is not available.
