Columbia is in NYC, the world's biggest financial center. This means easy access to all the biggest firms and the wide breath of opportunities.
At the same time, Columbia has multiple master programs producing hundreds of graduates aiming for the same kind of jobs that you apply for.
NYC and the tristate area is also home to other top ranked programs such as Baruch, Princeton,
CMU, Cornell, etc. This is to say you are one of thousands of people aiming for the same jobs every year. Unless you got in a program that has personal relationships with banks via alumni network with their own pipeline to unadvertised positions, getting a job is not a given.
Just go on LinkedIn and search for alumni of Columbia who graduated in Dec 2023 until now and you have a better idea.
NCSU is not superior the way you put it. It used its location and network with regional banks to their advantage. There are fewer competition in Charlotte so they crave out a niche for themselves.
For risk management roles, I think you can get them from any program just because competition is not that pierce. Some programs have a stronger focus on risk management where other have a more focus on sell-side pricing/stochastic.
Having a realistic expectation and clear eyed about the industry will prepare you to be a happier professional.
