Do the collage assures placement for the graduate's

Dear, there is no such college which assures placement. It complete depends on your performance. How you do in your college career and how you perform and present yourself during the interview. It is completely your hard work. Even the best colleges will not be able to provide placement to the students if they don't do well in their academics. All they can do is bring companies.

I will suggest you to specify about which college you want to know so that we can provide you with the name of the companies that take students from the particular college and what is the percentage of students getting a placement there.

Hi sooraj,
Although no college gives an assurance of placements but some colleges do have a 100% placement record in the past.
I would be able to give you further details if you mention the college you are graduating from.
