I am another poster. The decision is yours to make. I have similar background as you, just 5 years in banking. When I first graduated, I was never called up for a government job. As private grads, we will be disadvantaged to be in the government sector. Perhaps you are in the stage of your life where you value stability more. You have to think about what you value at this point and the pros and cons. If you have decided to switch, then don't look back and regret. There will always be trade offs in every decision you make. All the best.
