JEE Mains CRL is applicable for admission in NITs/IIITs and GFTIs.

Having a CRL of 3834, I believe you will secure good circuital as well as core branches at most of the NITs, including CSE and ECE at your Home State NIT.

Some of my suggestions would be take ECE at either of NIT Warangal/Calicut/Surathkal or IT at IIIT Allahabaf whichever is at your vicinity.

You can also prefer taking CSE at NIT Rourkela/Allahabad/Jaipur/Calicut  if you are in pursuing Computer Science and Engineering.

Perhaps if you are inclined towards Core Engineering and Technology choose Mechanical/Electrical Engineering at NIT Trichy.

Placements and career prospects are not a concern when it comes to old NITs. Most of the top MnCs including Amazon, Intel, Goldman Sachs and American Express regularly visit these campuses for Placements and in most case 90% of eligible students are placed.
