yes, of course there is a significant difference between all the campuses. The main campus being the best of all with largest campus area, more than sufficient facilities for campus life and quality teaching, while other campuses are a little less area wise.
join the NCR campus only if the location suits you. The NCR campus does have a nice lot of faculty members in every branch. but, some important changes have taken place.
for example:
no books are to be provided from this year.
so kindly double check these issues before taking admission to this college.
I suggest you to confirm if the degree to be provide will be of the main campus or the NCR campus.

Hi Pervez,
The Training and Placement Unit of the Institute is responsible for providing world class job opportunities to the undergraduate and postgraduate students after graduation for suitable jobs in the industry and various private and public sector organizations.
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.
Salary is a function of various factors - I.e. (I) the institute where you have completed your B.Tech + M.Tech. e.g. a graduate from a top institute will command a higher salary. (ii) Your work experience - organization and type of work profile (iii) city - a metropolitan city will have higher salaries as compared to smaller cities and towns. (iv) Your current organization - I.e. where you will be joining - an MNC usually has higher salaries as compared to other organizations. (v) Your work profile I.e. Manager/ AVP, etc. Thus one cannot allocate a figure.
Hope this information helps. Please feel free to revert.
Wish you luck.
