Tips For Facing The Interview

Tips For Facing The Interview :

ENTERING THE ROOM :

Prior to entering the room , adjust your attire.

Before entering , enquire by saying , " Please May I come In ".

If the door is closed before you enter , make sure you shut the door behind you softly.

Face the Panel confidently and wish the members.

If the members of the interview board want to shake hands, then offer a firm grip first maintaining eye contact and a smile.
sit down only when asked to do so by the panel. If the interviewers are standing , wait for them to sit down before sitting.
An alert interview would diffuse the tense situation with light hearted humor and immediately sat rapport with the interviewers.

ENTHUSIASM :

The interviewer normally pays more attention if you display an enthusiasm in whatever you say .
This enthusiasm comes across in the energetic way you put forward your ideas.
You Should maintain a cheerful disposition throughout the interview, i.e a pleasent countenance holds the interview interest.

HUMOR:
A little humor or wit thrown in the discussion occasionally enables the interviewers to look at the pleasant side of your personality . If it does come naturally do not contrive it.
Injecting humor in to the situation doesn't mean that you should keep telling jokes .It means to make a passing comment that , perhaps , makes the interviewer smile.

EYE CONTACT :

You Must maintain eye contact with the panel through out the interview.This shows your self confidence and honesty.
Many interviewees while answering . tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence.
Maintaining an eye contact is a difficult process . As the circumstances in an interview are different , the value of eye contact is tremendous in making person impact.

BE NATURAL :

Many interviewees adopt a stance which is not their natural self . It is amusing for interviewers when a candidate launches into an accent when he or she cannot sustain consistently through out the interview or adopt mannerisms that are inconsistent wit his/her personality. Interviewers appreciate a natural person rather than an actor. it is the best for you to talk in natural manner because then only can you appear.
gud luck!!
