The Biggest Body Language Mistakes in a interviewer

Being anxious in the interview hall

Nervousness often leads to uneasiness in the work environment.
Fidgeting builds an uncomfortable situation or is interpreted as tediousness.
You should try to greet people with a strong handshake which is a good sign of confidence. While a weak handshake can indicate your lack of confidence.

Checking the time

Don't check the time often. This will provide the bad impression that you are boredom.
If someone spends the time to meet you, respect that and do the same for them.

Crossing your arms 

You should keep your body language open and friendly instead of crossing your arms. The crossed hands can appear as distrustful and defensive.

Don't go to close to the interviewer!

You have to show some interest in another person while you don't need to be too close to make them uncomfortable.
