Dear Nandini ,

You can apply for Govt. Bank sectors like SBI, PNB ,RBI  etc. , appear for their individual entrance exams for Probationary Officer and clerical positions as a B.Com graduate as this field will be comfortable for you .

Well, some banking exams for Govt recruitment are as follows :

• SBI PO
• SBI CLERK
• IBPS PO
• IBPS CLERK
• RBI PO and others.

Well, if you are not interested in banking sectors , you can go for Railways, SSC (staff selection commission ) CGL  and other central govt exams .

Hope this answer helps !
