In terms of the research field, there are almost no placements opportunities in Engineering Physics at NIT Calicut. The only companies where you will be are allowed to apply for the placements are in the Consultancy services, Sales, etc. 

Basically, we can say that NIT Calicut has nothing to offer to the students of Physics. If you want a decent job, then you should work on your coding skills else, you will have to do the basic 8-7 jobs.

You can also apply for IIT JEE coaching institutes as these companies offer better salaries and less workload. If you wish to pursue higher studies in the future, you can get a side job at one of these coaching institutes and prepare for your entrance exams. This way you will be in touch with your subject and earn part-time.
