How to give self introduction in an interview as a fresher?

Starting with name age , qualification , work experiance, hobbies,
a common question is "tell me about yourself" which is what your self introduction is all about . 

You need to change this depending on who's asked the question and give an answer that is relevant to them and their needs.
The interviewer does not want to know about your personal life beyond name and interests. Give a short introduction about yourself; speak about your educational background, previous job positions you have held, brief introductions about your accomplishments etc. Speak at length about yourself covering all the major points briefly.
