B.Tech Placement

Yes, Amrita School of Engineering is definitely a good option to pursue your B.Tech. It's really important to choose a well-known college because there are hundreds of engineering colleges here. Amrita School of Engineering has foreign tie up and is quite well-known in India as well as in foreign. Well known companies come for placements but it all depends on how meritorious you are.

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.

UPES has a good placement record of mechatronics branch and students from UPES get offer from good companies like:
Birla Soft Technologies,
IBM,
Infosys,
Aveva Softwares,
Weatherford Drillng,
Caterpiller,
Cummins,
Escort Ltd,
HERE Maps,
JK Tyres, etcetera.
Around INR 4.5 LPA is the average package that a campus placed mechatronics student gets.

The chances of you getting placed will be doubled if you do your M.Tech or MS in material sciences or metallurgy. The demand for metallurgical engineers is growing these days. Government organisations like DRDO, DRDL, etc. offer a wide range of opportunities. Also, private companies like shell, Liners India, Tata Steel, Reliance, etc. offer some very interesting jobs. So all those students really interested in material science can take up this really interesting branch and stop worrying about the placements.
