B.Tech

No institute can guarantee you placements. It's just purely based on how you utilize your abilities and skills at the right time. I would suggest you to contact the training and placement department personally for accurate numbers. All the branches of engineering are equally good and have tremendous job opportunities. It entirely depends on how well you understand and handle the stream and increase your scope of growth. To decide on the course, you should analyse your strengths, career goals, interests, personality, aptitude and ability. If you decide based on these parameters you will put in your best effort and will be successful in your chosen field. Always remember, you should pursue a stream/course based on two things :
-your career goal, -the type of job you want to do.

There is no difference as both means same. Right after independence of India we had two types of universities, one that offers degrees in many fields like Sciences, Arts, Education and Engineering too, and the second set of universities (were named as institutes) offer only degrees in engineering. Universities those offer other degrees along with engineering named their engineering degree as BE (Bachelor of Engineering) and Institute constituted for only Engineering studies named their degree as B.Tech (Bachelor of Technology). Now as AICTE approve courses most of the courses are same and identical for BE and B.Tech. The universities those offering BE when started new courses named them to B.Tech too. Hope this suffice.
