Let me reason out to you

NIT Jamshedpur

*Pros

Excellent Placement in both Core and Non Core Sectors. Almost 90% placements in all Branches. Since last 3 years Batches of Mechanical, Metallurgical and Electrical have almost 100% Placements. Jamshedpur itself being an Industrial Hub, provides lots of opportunities in training and placement prospects.

Excellent Hostels and Mess Facilities with almost 70% Undergraduate Hostels having single occupancy.

*Cons

Poor Infrastructure and Maintenance of Administrative and Departmental Buildings.

Poor Research Facilities. NIT Jsr isnt a place to go if you are planning to pursue a Masters or Doctoral degree in future and planning a career in research. You will not find any motivation and impetus required in pursuing projects and research in campus.

Campus Life isnt as vibrant as top NITs and IITs, though NIT Jsr is steadily rising and has developed a good institute culture in last couple of years.

IIEST Shibpur

*Pros

Faculty and Research Facilities.

IIEST has excellent research potential and collaboration with top Institutes like IIT Kharagpur further ensures good projects and sponsored research in campus. Incase you plan to pursue Masters or Doctoral Degree, IIEST should be your preference. Till date 20%of every batch moves to US Universities and technical Institutes like IIT and IISc for higher studies. A large chunk of IIEST Alumini are settled in the United States, UK and are distinguished professionals , researchers and academicians, hence the Institute enjoys great International Outlook.

*Cons

Placements. Placement opportunities are quite bleak at IIEST especially in Core Branches like Mechanical, Civil and Metallurgy, when compared to that of NIT Jamshedpur. However Circuital branches like CSE and IT enjoy good placements. Still a considerable number of students stay unplaced and prepare for GATE/GRE/IES/CAT/etc Competitive Exams.

IIEST Shibpur, BIT Mesra are one of the oldest technical institutes of the country, but after start of the IIT-NIT System, it fails to gain attention and if often only considered by students from nearby states of West Bengal, Odisha and Jharkhand around. Hence you wont find any diversity or strong college culture there.

My advice will be to prefer NIT Jamshedpur above IIEST Shibpur.
