Jasmeet, you haven't mentioned which State or which Government Polytechnic College are you studying from to check the guidelines. Nevertheless, all Polytechnic Students as a part of their Industrial training need to work or be trained under any Registered Institute. And in return, you will be be awarded a training certificate and the project that you worked on in that Institution. So you have to reach out to local Institutions or Start ups that you might have in your area to check the possibility of a training session. It is like an Internship and it might be a paid or an unpaid one. Or you can check in apps like Internshala regarding relevant internships or apprentice. You can try this or you can reach out to your faculty to check if anyone of them can refer any Institution or a source to you. Most of the times, referrals work as well.
