If you prefer to continue to studies, you can do Post Graduate courses and then obtain a Ph.D. You have lots of options during this P.G course like M.S/ M.Tech, IAS/IPS, Navy/NDA and Finance related courses like MBA.

M.S/M.Tech:

GATE: Conducted by one of seven Indian Institutes of Technology in rotation, Graduate Aptitude Test in Engineering (GATE) is an annual exam for admission to M.Tech and M.S. programmes in most engineering institutes in India[citation needed]. It is regarded as a benchmark test for engineering graduates in India [citation needed]. This examination is coordinated by a committee, comprising of Indian Institute of Science, Bangalore and seven Indian Institutes of Technology on behalf of the National Coordinating Board - GATE, Department of Education, and Government of India. The pattern and syllabus are usually based on a candidate's B.Tech. Or BE syllabus. Minimum eligibility for appearing in this exam is usually a B.Tech, BE, B. Arch. or Masc. The exam is usually conducted on second Sunday of February.

If you prefer doing P.G in your field of study, you can go for M.S/M.Tech. If you are ready to go outside India and financially sound you can prefer M.S. You need to appear for GRE/TOEFL for doing M.S in Foreign countries.

GRE: The Graduate Record Examination or GRE is a standardized test that is an admissions requirement for many graduate schools in English speaking countries. It is created and administered by the Educational Testing Service and is similar in format and content to the SAT. It is a computer based Online Test. The percentile scored in this exam will decide your future in doing M.S in foreign nations.

TOEFL: The Test of English as a Foreign Language (or TOEFL®, pronounced "toe-full" or sometimes "toffle") evaluates the potential success of an individual to use and understand Standard American English at a college level. It is required for non-native applicants at many English-speaking colleges and universities. A TOEFL score is valid for two years and then is deleted from the official database.

This is the most preferred route by engineering students in education after B.Tech.

Software industry: What ever the branch you are in during your engineering you can get into a software industry with simply communication skills. It is good if you get a job during the campus placements itself because it is really difficult to find a job after you come out of the college.
