Hey yall im doing my btech degree in civil engineering ,well this was a decision based on my cousin as i was not interested in any particular course as such but i think i have accepted it now .after this i wish to study anything, i wish to take mba . What do you guys think about it ? (I dont have an interest or opinion on my own so i thought ill ask you guys and curate pros and cons) .what all job can i expect if i do my mba and hows the pay .The thing is generally the pay is quite low for civil engineering
