I got 19k rank which nit mechanical
Hello Ganesh...
Well, Getting a good NIT in this rank wouldn’t be easy. But you can try for NIT Bhopal, SVNIT, NIT Kurukshetra, NIT Jalandhar, NIT Rourkela, NIT Patna, NIT Durgapur ( The names metioned above are in decreasing preference).
But, if you can budge a little bit and an NIT tag is not so important for you. IIIT-Amethi is a good option as it has good placement scenario because the last year students of IIIT-Amethi are shifted to IIIT-Allahabad campus and so the companies coming for recruitment purposes in IIIT-Allahabad also consider Amethi students without any biasness.
Best of luck.
