How is IBPS SO different from IBPS PO ?

IBPS conducts the PO examination for the recruitment of candidates for the role of Probationary Officers at various participating institutes. Probationary Officers are entry level officers who start their role as a officer at various banks. IBPS SO is conducted for the recruitment of Specialist Officers. As the name suggests, Specialist officers are hired for special roles in the banks and hence requires some substantial amount of experience.
