@Mani Joharalmost 85% cgl group B officers become group A officer after 20 yrs. The equivalent position in bank is scale 5 manager itself. In banks, they are known as AGM or RM. The perks of a group A officer is not tangible. The salary of a group b officer joined 30 yrs ago through CGL is more than 1.75 lacs including HRA in every metro city. When you notice advertisement of any deputation post in Central government, you can check the equivalent post in Bank. As for example, for an assistant director post in ED needs a scale 4 manager of any PSB.
