The chances of placement for an MSc in Physics student at IIT Roorkee depend on his mode of admission.

Through JEE: If you have taken admission through JEE, you are well-versed in more than just physics. Your knowledge base comprises math, electronics, computer programming, etc. You can use these in your favor to secure a decent job in the industry or IT. To enter the IT sector, opt for extra courses like DBMS as audit courses as these might improve your credibility during the interviews.

Through JAM: If you got admission through JAM and try looking for some good internship opportunities or sit for some competitive exams to appear more employable. You can also enter Academia and become a teacher at a decent University apart from IIT/NIT. 

It’s okay to accept that the MSc program won’t make you an Engineer and you will have to resort to other things to upgrade your CV. To secure a managerial position, you can look for positions of responsibility on campus. You can show your interest in the particular field through extra courses, external coaching, competitions, and vacation internships/jobs. 

Instead of losing all hope in the degree, it’s better to determine your interest and steer your resume and skills in that direction.
