hi,

see once you complete your graduation course in any discipline you are eligible to give ssc cgl, rbi assistant, sbi po, sbi clerk etc exams. however data science deals with statistics and it has good career scope in mncs companies,. but for government sector , there is less recruitment now for data science specialist. however data science includes topics like statistics, probability, set theory and discreet mathematics. so you should take bsc in data science if you have eagerness to learnt these courses.
