Well... GA/MA program usually have thousands of applicants, and in the end only 20 to 25 are chosen each batch (DBS, JP Morgan Chase etc). To have at least a 2nd upper honors is a must. The rest is up to how you can speak and answer questions through the case studies and panels.

Every techie is fundamentally strong, usually. But most of them are introverts that cannot manage their weakness, that is to be outspoken. These programs look for technical people that are also outspoken and has leadership potential. CCA is not required but may help applicants market themselves.
