Advice on placement in AI domain for a non-CS fresher

I am a 3rd year mechanical engineering student in VIT,chennai. I want to work in the field of AI. We have placements starting in the fall semester 2020. I don’t know much about different companies. Can you guide me which companies should i target, how should i prepare and which courses to get certified in to get a high paying job. Currently i am doing GUVI Artificial intelligence with deep learning certification course and an AI developer remote internship in smartBridge online.I can program in c,c++,python. If you could provide me the list of companies,that would be great.
