Dear Candidate, hope you are doing fine.

For best connections for candidates looking for internship can be found out on LinkedIn. Network with people within your domain, connect with people you will help you connect & get an opportunity presented for yourself. Try asking for internship opportunities & also search the same on internet. There are various sites which offer internship for digital marketing. You can get in touch with people who have MA in digital marketing & are well ahead in their career via LinkedIn.

In my opinion, it's all about how well you understand the audience & the way you can connect with them. Networking on LinkedIn is the best.

Thanks.
