Considering a Domestic MBA

I graduated from Daewon Foreign Language High School and Sookmyung Women's University with a degree in Business Administration.
I am currently in my 4th year working in marketing at an affiliate of the Shinsegae Group.
I am 30 years old and am considering applying for the Korea University MBA (KMBA) for career expansion, job switching, and personal development.
However, I am debating whether it is truly helpful in terms of networking and career advancement, or if it is simply a program where anyone can get in as long as they pay the tuition and provides no real value.
In the job market, would the combination of a Sookmyung Business degree + a Korea University MBA carry the same weight as an undergraduate degree from a "Jung-Kyung-Oi-Si" university?
