Dress Up Professionally
Not Casual ,Not Gaudy but Formal and Simple
Be Early
This  will give you time to relax,revise and settle down.The last minute rush  will only add tension and then the chain reaction of disaster.
2)Introduction
State your name with a firm handshake and a smile.Maitain eye contact when you do that and through out the interview.Wish  them Good Morning/Afternoon/Evening .Though your technical rounds would  have started in the morning ,your HR round might happen in the  evening.So  be attentive and wish appropriately.
Record and Remember Their Names
This  will show them your attentiveness and memory skills , when they ask you who took your previous rounds or when the HR asks - Who  took your technical round ?. Names are also necessary when  you follow up later on for the result.Faces are easier to remember than  names. So a quick and easy way to remember names is to associate their names with their faces and the combination with  someone famous or someone you already know or something funny.The  funnier the association the easier to remember.
3)The Intermission
Time  in between different rounds of the interview process should be used to relax  and concentrate.Here is my article on the topic - stay focussed while you wait.
4)The End - Thank and Note
The  end in most cases is a beginning to follow up.So make sure you  thank them for their time and get their contact details.Write down the HRs full name ,email address and phone number.Double check and confirm the  details you have written down.While you get frustrated and give up as you wait for  the result, it could just be a delay due to a required higher  management approval.So having the contact details will keep you up to date and give you some peace of mind.
