Hi you can take a career assessment test to see if your personality, interest and aptitude suits management or civil engineering https://allegiance-educare.in/plans
(1) Masters in Civil engineering might get you a job quickly abroad since freshers get technical jobs quickly (1) Construction management is also a good option if you want to shift to management. You can get a job quickly based on your civil engineering degree, but usually companies prefer experience for management jobs, so make sure you do your masters from a good B School (3) Since you have no knowledge about finance, you should first gain some experience or some certifications in Finance and then go abroad for your Masters in Finance, this would be a better way to get jobs in Finance quickly.
