It's tough to find a college in Jharkhand that promises you'll definitely get a great job after graduation. No school can really promise that. But, I can tell you about some good colleges that usually have pretty good placement results and fit your budget.

1.Birla Institute of Technology(BIT), Mesra (Ranchi )

Known for its strong placement success, BIT Mesra provides diverse B.Tech programs (Computer Science, Electrical, Mechanical, etc.). While fees depend on the specific program, they are usually within your range. It's best to confirm current fees on their website. They have a very effective placement cell that brings in many leading recruiters.

2.National Institution of Technology (NIT), Jamshedpur

Another excellent option in Jharkhand is NIT Jamshedpur, known for its strong placement history and diverse B.Tech programs. As a central government institution, its fees are generally more reasonable. It also has a very effective placement cell.

3.Government College of Engineering, Ramgarh

Being a government college, the fees are significantly lower, making it an accessible option. While placement records might not match those of NIT or BIT, it's still a valuable choice, especially for students seeking budget-friendly education.

4. Cambridge Institute of Technology, Ranchi

This institute, a private option, has established a good reputation in the region. They provide a range of B.Tech programs, with a focus on practical, industry-related skills. Before applying, thoroughly examine their placement history and fee schedule.

I hope this helps.
