Hi Shubham!

Yes, you are absolutely right! In this pandemic situation, companies are not even allowing their own employees to work from office, so they cannot allow other students at their place for training. I would suggest you to gain the knowledge in online mode, you can get the videos or lectures of all the equipment used in the field in online mode. But if you want to add a certificate of internship in your CV, then online internship is a good option in this pandemic situation.

Hope it helps to clear your dilemma, thankyou!
