SSC CGL vs MBA ?

hello everyone, im 20f, final year B.Tech ECE, graduating 2027. Torn between SSC-CGL (Group B) and prepping for CAT/MBA as a fresher.

not really inclined towards either(both have similar syllabus) but since both exams are about a year out, and i have a year left of college too. only thing im sure of: i dont want a gap year after graduating. what would be the wiser choice today?
