Agriculture and Food Engineering faces no competition in the Indian market and thus its students usually target higher studies from foreign universities. Basically, no other IIT has had this branch till now.
The course curriculum includes basic principles of chemical engineering, mechanical engineering, and civil engineering, but each of these is taught in agricultural aspects.
Since the students of this course do not specialize in any branch, the placement scenario of this branch is very poor. Agricultural Engineering companies might have a special interest in you but the main problem is this branch is not known to many top companies. Eventually, there are only a very few core companies that offer placements.
The worst part is that even companies offering non-core jobs that are open for students of all branches don’t consider students of this specific branch. So it all depends on your individual performance and your profile.
Hence the scope of non-core jobs in this department is decent and depends mostly on your individual profile and performance.
