My sister was a student of the Energy Engineering branch at NIT Trichy and is currently working for Robert Bosch. Her batch was placed decently and she claims that most students with a Mechanical and Electrical background got good job offers. Is the chemical and biotechnology students that suffered the most. For them, it’s better to pursue research than look for a job.
In 2018, her entire batch of 11 students was placed mainly because all the students were from the Electrical or Mechanical branch.
So we can say that the placement scenario of Energy Engineering at NIT Trichy is decent and the job opportunities depend on your profile and background.
