Hi Aspirant,
Civil Engineering has a large scope in the government sector. You can go for GATE,IES,Exams of other PSU's,State government job exams etc.
However,the competition in this field is very tough and it is not easy to get through.
You should definitely continue your efforts because it does have a very bright future but also taking a job in the private sector and then simultaneously preparing can be the best way to continue.
Hope this helps.
