VIT Vellore

Well nothing is sure in the world. However, VIT increases your chances of a good placement with a decent salary. Generally people get jobs around Rs 5-7 lakhs. Some bright nuts even get Rs 20 lakhs. So it depends on you how good are you?
VIT pulls in a lot of companies and almost all the major MNCs in India. So you will get the best of opportunities, it just depends how well you use it.

As far as I know Manipal is better than VIT, but there are pros and cons with every University. There are things such as publishing research paper and stuff in which VIT is better than Mainipal, but in many aspects Manipal is much better than VIT as far as Academics and extra curricular activities are concerned.

You should go for DAIICT, GANDHINAGAR because the placement opportunities of this institute are excellent. According to last year's placement survey, 3 students got placed with the highest salary of 40 lakhs in AMAZON INDIA from this institute.

Chances are very low to get a call from XIME. A good academic profile and work experience (if any) will help in enhancing your chance to get a call. Atleast 70-75 percentile gives a good chance to get a call. Another chance is, you can apply through CMAT score. For VIT you can expect a call. 60 percentile is on the lower cut off taken for admission in VIT. So, you have a chance to get a call and a good performance in WAT-PI/GD-PI will enhance your chances. Good Luck.
