Anilbro, don't make a mistake working too much in gas station. Give as much time as you can for job search. Just a reminder,  give emphasis in certain field(only civil or structure or environment). Don't declare yourself an expert ...usually this kind of mistake makes you vulnerable  since u r a fresh graduate. But your resume and coverletter should reflect your talent and willingness to learn and capability of working in group. In interviews be very confident even if you feel u don't know the exact answer. And don't worry, job market is never gonna go down for civil engineers. Have faith, keep tryin..  mark my words...when the time comes u will get several offers...GOOD LUCK
