The highest being 43.3 lakhs per annum. Companies like Tata Motors, TATA Steel, TATA Advanced Systems, L&T Pvt. Ltd., L&T Construction, etc have visited the campus for placement drive.

IIT Delhi ranks 2nd in the Engineering category by NIRF 2019 Rankings. Biochemical Engineering and Biotechnology in IIT Delhi has a significant role that was played by biochemical engineers and biotechnologists in future industrial development of biotechnology-related processes. Today, the Department provides a structure for an integrated approach towards education, research, and development of various bioprocesses. For MTech, the students must have a BTech in Chemical or Biochemical Engineering.

Biotechnology from IIT is a good option but there is not much scope in India but has more abroad. A student requires a good CGPA and maintains a good CV to land up a good consultancy job or admission at top MBA colleges. It is a five-year course and requires 1 extra year to complete BTech, unlike other Engineering programs.

Biotechnology and EE are two very different branches to be compared with each other. But if you are not sure which branch you like more here are a few pointers about both the colleges which may help you make the decision.

IIT Bhubaneswar offers decent placements. The placement for EE was 86% in 2019 with an average salary of 11.44 LPA. IIT Bhubaneswar is divided into many schools instead of branches. School of Electrical Science has Electrical Engineering, Electronics and Communication Engineering, Instrumentation Engineering, Computer Science, and Knowledge Engineering. The infrastructure of IIT Bhubaneswar is good as it is newly built. Faculty members are qualified and well experienced. IIT Bhubaneswar is located outside Bhubaneswar city and the campus offers a good academic environment away from the city.

IIT Delhi is one of the top 3 IITs. The placements are better if we compare it to IIT Bhubaneswar with an average package of 16 LPA. Biotechnology is a very diverse course. Multiple options are available if one wants to go into research. In this department, the placements are not so good. Core companies hardly come for placements. But placements for non-core companies are open. The campus is small as compared to other IITs but the infrastructure is quite good. The college is right in the middle of the city and provides easy connectivity to another place.

Now, if you are looking for better college life go for IIT Delhi but if you are interested in EE go for IIT Bhubaneswar.
