Since it is gvt job you dnt have pressure to achieve your targets. You can give time your kids and family. But atleast 10am to 6pm time will be spent in office. Since you are female employee then you will get preference in transfers and postings. . For kids you can send them creche or day care center .
Since it is govt job so one thing is sure that once you become employee of his bank, even merger or amalganation will be held, but your job will be there always. Job security is always there. You can grow your kids. After 5 yrs of job you can get child care leave also for your kids for 2 yrs.
Work culture and work pressure is a little bit more than central govt job. it all depends on oneself how much sincere you want to take everything
