Choose a good position
At an interview, you will normally be directed to a specific seat. However, interviews can often be conducted in oversized environments.

Make sure you choose a seat which enables you to see everyone involved without having to rotate your head exaggeratedly. In most cases, it may be best to hover around to see which chairs the interviewers are aiming for before making your selection.

If there is a window, choose a chair that faces it so that your face is lit from the front, unless there is good lighting all around. If you turn your back to the window, the interviewers may see you in sepia!

Don’t be afraid to “own the space”
Just because you are under observation, it does not mean that you should recoil in a corner. It is okay to stand or sit with your legs slightly apart, and in fact, it is a sign of confidence (don’t overdo it though, it would become indecent!)

Limit your hand and arm movement
It is perfectly okay to move your arms and hands around, and if that is the way that you normally behave then don’t try to become someone else. Your personality and enthusiasm are as important as everything else. However make sure that such movements do not become distracting and do not take the attention from your face.

To achieve this, make sure that you don’t overdo it and that your movements are limited to the corridor in front of you, never higher than your chest, and never under the table. If there is no table, you can let your hands go as far down as your lap. If your hands go outside towards the left or right, your interviewers will follow them and may stop concentrating on you.

Maintain eye contact
If you don’t make eye contact, you will come across as evasive and insecure. If you stare at people too much, you will make them insecure. There are two situations here: either you are being interviewed by just one person, in which case you will have no choice but to look at them all the time; or you are being interviewed by more than one person.

If this case, then look mostly at the person who is asking you the question, and occasionally glance aside to involve the others (they will be grateful that you are trying to involve them into the conversation even if they have not asked that particular question). Beware of the props If you have a pen with you, avoid fiddling with it.

Mirror the interviewer’s behaviour
Mirroring  to someone is an indication that there is a connection. It would normally happen normally but you may be able to influence it too, if only to give the interviewer that impression.
