You want to change from engineering to journalism career. How many years of the engineering course have you completed. What is the money you have spent so far.
A bird in hand is worth two in the bush. In our case you have half of engineering and the dreams of a journalism degree and job. I would suggest, while you are deciding stay on the course, complete it. Having a bachelor's degree gives you a golden fall back chance of plan B, if your dream career does not take off. You will realize the value of this only when you face this situation.
Journalism and mass media communication is all about having the right skill set of intution, tenacity, presence of mind, thinking on the feet, ability to do odd hours, be on the move, take calculated risks and plenty of networking and contacts to get a tip off, breaking news etc. This sector is also very competetive, many newcomers work under a popular channel as research and back office support kind of role.
Currently, in India, a candidate can pursue one regular stream degree and one distance learning course. Why not think of utilizing this chance to complete you BE and also enroll for a journalism course from Indira Gandhi National Open University. Please check out the school of journalism and new media studies (http://www.ignou.ac.in/ignou/aboutignou/school/sojnms/introduction). This degree would be UGC recognized.
You need to have a good command of English and regional languages, be able to write creative, be expressive and outgoing and have good computer and presentation skills.You can browse for more inputs on starting a career in journalism (http://www.journalismdegree.com/become-a-journalist/).

During the final year of your bachealor/ during internship, if you find a key area of interest, then give a thought about doing a further post-graduate course in media/journalism.You can choose from, Indian Institute of Mass communication, Asian college of journalism, Mudra Institute of Communication, Ahmadabad etc. This would help you to climb up the career ladder.
