Lot of private sector ancillary industries are developing to support ISRO and DRDO indigenous technology development effort. India has well developed aircraft and other aviation systems production companies in both Public and private sector. Therefore, Aerospace Engineering graduates have good job opportunities in DRDO, ISRO, HAL etc organisations. In additions Aerspace engineers are employed by Indian Air Force, Airlines, specialized aircraft maintenance companies. Lot of multinational companies have offshore centres which employ Aerospace engineering graduates. Lot of IT companies also employ Aerospace graduates in their Engineering vertical.

Hello Archita,
An electronic engineer can find a job in consumer electronics manufacturing organization, telecommunication & IT industries, health care equipment manufacturing, mobile communication(2G,3G,4G), tnternet technologies, power electronics and other industries like steel, petroleum and chemical industry, directing control and testing production process.
Electrical Technicians and technologists can specialize in technical sales, product representation, systems management, the design and manufacture of electronic devices and systems, or the installation, maintenance and repair of electronic systems and equipment.
They may also work with computers and electronic equipment in the medical, manufacturing, industrial control, telecommunications, aeronautical and military fields.
ECE also have several job openings & good pay-packages as compared to other branches.
Electronics and Communication Engineers are acquired by top recruiters (both private and government) like DMRC, Siemens, Motorola, Intel, Texas Instruments, BEL, ISRO, DRDO, Accenture, Wipro, HCL Technologies, Nvidia, Samsung, Tech Mahindra, Infosys, TCS, Conexant, MTNL, AIR, BSNL, Indian Air force, Indian Navy, Railways, Bharat Electronics Ltd and Flextronics and Philips Electronics.

It varies from person to person depending up on the branch you opted for Bachelor's. I am sorry to inform you that 57% is really low if you wish to get placed in some good company (government/private). So buck up. Try hard to improve your percentage. If you wish to get placed through campus interviews, you need to have at least 65%.
If you don't wish to go through placement drives, you have several other options. First, you may start preparing for GATE or NET exams. Through these exams, you will be able to pursue M.Tech if you want to enter technical field else it will help you to get into PSUs which are the preference of most of the aspirants.
If you are not interested in the technical field then you can prepare for exams like CAT, XAT, etc. These exams will help you bag the management studies. These studies will help you start your business or will aid you in getting management related posts in the firms or organisations.
If you want to settle out of India then you should prepare for exams like GRE, TOEFL, GMAT, etc. After this, you may apply for Master's (MS) abroad. Thereby, you may apply for some job as per your preference.
I also want to add that after M.Tech you may go for Ph.D. These will help you to land into some recognised research centres like BARC, CSIR, etc.
You might also go for academics, for example being a faculty in some college. Starting salary might get Rs.12000. After M.Tech faculties get around Rs25000. After PhD the salary increases further, and the individual might get a chance to become HOD.
All the Best for your future ahead!
