I might have missed a few companies.
The highest package of this year was from West Line Ship Management (21.6 LPA). I don't know how the placements are there in IIT'sand NIT's for mechanical but here in VIT, these are the companies visited this year till now. I hope few more companies may join in this list at the end of this 2016 academic year because still one more semester is there to complete this academic year.
NOTE: All these above-mentioned companies had taken in single digit numbers (min 1- max 10) and package ranging (3LPA-12LPA)
In simple words, companies do come, it's up to you to get placed.

B.Tech in ME from BITS PILANI is better option then doing it from VIT due to following concerns
BITS Pilani is a preferred destination to recruit from, for a large number of companies. We feel validated in the quality of education and experience we provide to our students when a majority of our students are successfully placed on campus. Each of our programmes are designed to give our students a balanced education with theory as well as practical knowledge. In addition, they are encouraged to participate in extra curricular activities as it helps them develop soft skills and develop well rounded personalities. It is this that differentiates our students and makes them a valuable part of any company they join
Infrastructure: The College is under renovation and till 2020 it will be among the best colleges of India in terms of education as well as infrastructure. Renovated hostels have Wi-Fi facility. Library is world class. It has A.C. halls as well as non-A.C. rooms. Hostel rooms are good in condition. Labs and classrooms are not in a very good condition but after the renovation, they will be.
Sports facilities are very good. A separate area is being alloted for each and every sport.
Faculty: Faculty of the college is unlike those of other private colleges. They are very knowledgeable, helping and motivating.
The college has modern technology like projectors, videos are used to give examples or to explain the applications. Student to faculty ratio is 30:1 which is good enough. The course curriculum is good. Regular surveys are conducted to check if the students are facing any problems related to academics.

Why Recruit from BITS

The program exposes them to real life applications of their course work and teaches them to work in a collaborative environment. The Practice School gives students the vital experience needed to adapt quickly to careers in industry.
Balanced personalities - We believe wholeheartedly in helping students develop to their potential in every field of their interest. Soft skill development is made part of class-room experience through presentation and open ended learning components.
Extracurricular activities, student managed clubs and events give them further avenues to express themselves and develop skills beyond academics.

First of all, let me make it clear to my fellow students that VIT, Pune is indeed Vishwakarma Institute of Technology and not Vellore Institute of Technology. Now coming to the question, both of these colleges are pretty good in terms of the quality of education they provide. Pune Institute of Computer Technology (PICT) was specially founded for imparting education in computer science and IT. It provides only three courses in B.Tech which are computer engineering, electronics and telecommunication and information technology while VIT provides degrees in almost all conventional branches. Talking about academics, PICT has an edge when it comes to CSE and IT. I have some friends pursuing IT there who confirmed upon this. The quality of education is pretty good. VIT also is a well-reputed college and has a high demand for CSE and IT. Apart from that, VIT is known for its extra curricular activities and campus life as such. I would suggest going through the syllabus of both the colleges and taking into consideration factors like location, campus, and future goals before making a decision. Best of luck!
