Hello,
So among the three institutes THAPAR and VIT are private colleges where as LNMIIT is non - profit institute under the government of Rajasthan. Placements are not that great in VIT as they show but its not bad either but in comparison to LNMIIT and THAPAR it is not so good as the other two. LNMIIT and THAPAR have almost the same top placements. If you are really into coding LNMIIT is way better and in my opinion it is good for CSE department.
Good luck.
