Hello Aspirant.

Its a totally relative matter.Someone who likes construction of buildings,bridges,roads will prefer Civil engineering and someone who has interest in information and communication technology,softwares will prefer Electronics and communication engineering.But the hard truth is unless you are studying in a very good engineering colleges(like IIT,NIT,ISM,VIT,JU,IIEST Shibpur etc) it will be difficult for someone to get placed in a Civil engineering company.If you want do higher studies then it won’t matter much in case of B.Tech.But choosing the correct stream is one of the most imortant stepping stones for an engineering student in India.There will be plenty of opportunities for an ECE student in terms of placement and higher studies even if he/she has done B.Tech from a tier 3 engineering college. At the end I'll say that  its totally depends on your area of interest. If you still feel confused, then here I'm giving details about future after both courses: -

.Future after ECE: -

.An electronic engineer can find a job in Consumer electronics manufacturing organization , Telecommunication & IT industries, Health care equipment manufacturing , Mobile communication(2G,3G,4G), Internet 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.

.Future after civil engineering: -

.Project Manager

.Assistant Project Manager

.Site Engineer

.Civil Engineer

.Assistant Civil Engineer

.Purchase and Quality control Executive

.Planning and Design Officer

Graduates may also take up teaching job after completing M.Tech. course. Also, pursuing PhD courses will help build a career in the Research sector.

I hope my answer will help you to choose right course for you. All the best.
