Institute of Engineering and Technology (IET), Dr. A.P.J. Abdul Kalam Technical University

No chance, but keep an eye on the counselling process and think about some other options as well.

With an OBC rank of 2435 your general rank would be in between 10k-12k (a simple guess), I'm sorry to say with this rank getting into IET is next to impossible so don't hold any false hopes you can get into JSS and here also getting CS and IT would be tough for you.
Getting any other govt college is also difficult and even if you get one you might end up in not so favourable branch.
At last, what I would suggest is that if you have a one more chance in JEE MAINS then go for it because believe me giving another year to study is worth regretting about the college you would be with this rank to make myself clear try avoiding AKTU.

Go for CS or ECE Jaypee Noida if you want better infrastructure exposure and if money is not a constraint. Consult the seniors of Jaypee regarding placements. I can only tell you that IET Lucknow will definitely provide you ample opportunities as far as placement is concerned.

You have less chances to get a government college but you can take admission in good private colleges.

Yes, your rank is far good and you have a fair chance to get admission in IET.
