HR Interview Tips : Entering the room

Prior to the entering the door, adjust your attire so that it falls well.
Before entering enquire by saying, "May I come in sir/madam".
If the door was closed before you entered, make sure you shut the door behind you softly.
Face the panel and confidently say 'Good day sir/madam'.
If the members of the interview board want to shake hands, then offer a firm grip first maintaining eye contact and a smile.
Seek permission to sit down. If the interviewers are standing, wait for them to sit down first before sitting.
An alert interviewee would diffuse the tense situation with light-hearted humor and immediately set rapport with the interviewers.
