You should start with your education,Hobbies, 
Interests,Skills and finally family background.

and the final one is
8)aim

if u perfect with this 8 points u will definitely select in
this round

Any one should start with addressing suitable time when you 
have gone for an Interview,I think Freshers can start with 
with every thing in detail but an experienced people,they 
do not have so much of time in interview and Interviewer as 
well, so In this case any one should start with 
Gradutation,P.G.Qualification and their total experience in 
brief with their job profile and  in last family background.

This is encounter to PAVAN. Who posted his answer for "Tell 
Me about yourself?".

Pavan when we submit our resume to interview, I hope most 
of the detail relate to us mention in resume. However, the 
interviewer asked this question to you for check the 
communication skill you have with you. Do, not bother to 
tell any information that related to you. Of course we need 
to start with our name only. Then you can proceed with xyz.
