can i get best career with civil engineering course?

There will always be a need for designing and building bridges and tunnels. As for whether you can get a job, you can get a job anywhere, assuming the economy is decent, the industry is where you are looking and you get a good education and good references. There is no magic bullet for education and there are few guaranteed jobs - and if they are guaranteed, it's not because of one course or another, it's because of connections or demand.
