Aware of the Body Language you should know before your next job interview

Aware of the Body Language you should know before your next job interview
Here are 11 basic facts on body language which might help you a lot while preparing yourself for job interviews.
Most of us aren't aware of our body language, especially when we're in a stressful situation — but interviewers are trained to read it.
It is important to have body awareness before you go into an interview, In fact, there are many actions and habits that we should consider doing or avoid doing to tell the right story during the interview setting.
1. Feel good about your wardrobe and wear clothes that 'show you in your best lighting'.
2. Place your feet on the floor.
3. Sit still or you'll come off as a nervous person.
4. Place your hands on your knees.
5. Sit a bit forward to show that you're interested and serious about the interview.
6. Folding your arms will make you seem unfriendly.
7. Playing with your hair or cracking your knuckles can be extremely distracting to your interviewer.
8. Putting your hands in your pockets makes you look 'messy'
9. Don't invade the interviewer's space and keep your hands and body parts on your side of the desk
10. Use props to help you look more comfortable
11. Staring will make you look too intense and unnatural.
In a conversation, never fully lock eyes with people. Bentley said. We talk, we look people in the eyes, we have a thought, and we look away. We look to the right, and we look to the left. When you start staring at them, you start "to look a little crazy. If you feel like you are looking the person in the eye too long, hold it one more second and break away.
The above are only a few basic tips on body language "Do's and Don'ts" for a job interview. You can easily acquire them if you take a little conscious step ahead.
Hope, you enjoyed reading this post.
Have a great day
