1.  A Weak Handshake

This point couldn't be more important for anyone with an upcoming job interview. A flimsy handshake can be a real first impression killer. In his research, psychologist William F. Chaplin found that people with a weak handshake are instantly judged as being shy, anxious, uninterested, or, even completely incompetent! That's definitely not how you want others to see you, is it? Another common mistake people make is holding someone's hand for too long.

Awkward! If you're gonna give the right impression of confidence AND capability, remember to grip the other person's hand firmly, and for no longer than two seconds. That'll put you on the road to success!

2. Keeping Your Hands In The Wrong Position

If you're ever sitting in front of a group of people, whether it be at a business meeting, or at some conference, you've got to be mindful of where you keep your hands...

You can put them on your lap, but never keep them in your pockets, because this gives the impression that you're hiding something. If you place your hands on the table, don't squeeze them too tightly, or leave them flat with your palms down. This makes people feel like you want to control them!

Also, don't forget about the role that culture plays here. while gently folding your hands on the table is totally okay in the Western world, this position is considered rude in Japan and India. Do your research on the customs and culture before you visit another country. This will help you avoid any uncomfortable situations.

3. Chewing Gum

You've got to admit that it's incredibly annoying, and distracting when you're talking to someone, and they're chomping on a piece of gum! Put this irritating behaviour into a formal situation, or a first-time encounter with someone, and it becomes even more inappropriate. Chewing on gum, makes you look immature, self-centred, and somewhat lowbrow!

So don't even think about it for a job interview. You want to show your best qualities, not your indifference towards your potential employer! On the flip side, a new study has found that in casual situations, people chewing gum are usually perceived as more friendly and approachable. So be careful with this one, it can either help or hurt you.

4. Avoiding Eye Contact

Eye contact has an unbelievably powerful influence on how we view someone. A 2007 study, showed that people who maintain eye contact during a conversation, are often seen as more confident, attentive, intelligent, and trustworthy. People that avoid eye contact, on the other hand, are viewed as less sincere, more anxious, and even unattractive!

It doesn't mean you have to stare people down like a creep, Just don't be afraid to lock eyes with another person from time to time, instead of constantly looking around ! Especially when you meet them for the first time.
