Hello Shreeram,
You are indeed eligible for getting jobs with NGO's. Anthropology is a good subject. But, for getting jobs with NGO, I would advise you to register with placement agencies. Also, if your college has placement cell then I am sure they too will be doing needful.

Please participate in the counselling conducted by AU from June 5th onwards.

Yes, you can pursue M.Sc Physics after completing B.Tech. I have known a few cases like that. In fact, a person who has scored very well and can clear the NET JEST or exams alike can even directly pursue Ph.D. To pursue M.Sc-Physics, you need only a graduation degree in relevant subject.
