Although every college says that they provide placements, but it is up to you to get marks in your graduation and how you give your interviews.

Hi Sanjeev Kumar,
It's not mentioned on the website. Kindly request you to contact the college authorities.

Getting IET at this rank is not possible as your rank is too high. For that, I'll prefer you to opt any other govt college or if you want IET only then you can wait till the spot round of the counselling.

Yes, you can easily get this college at this rank but as the seats are quite low for this branch then it would be possible that you to wait for the last round for the counselling but at this rank you will definitely get this college.

See, the best college among all the above colleges is KIET as this college offers you placements that are far better than any other college in the list mentioned by you.

Yes, you can easily get that college, but the problem is that you can get much better college than the BBDIT, as with this rank, you can easily get ABES and many other colleges.
