Trying too hard
Although it's tempting to try to prove your worth immediately, trying to do this too fast can make you look arrogant, Fast Company advises. Instead, ask a lot of questions, which will help you learn the ropes as well as build trust with your colleagues.
Not clarifying expectations
The Public Relations Society of America recommends meeting with your manager to discuss your responsibilities, priorities, how your performance will be evaluated and how your role fits into the company's goals. You'll also want to request ongoing feedback to ensure that you're staying on the right track.
You can start a new job with a plan for success, but you can't leave people out of the equation, according to Time. Know whose help you need to get your work done, and build productive relationships with these employees.
Taking on more than you can handle
In an effort to prove your worth, you may be tempted to take on more responsibility than you can handle. Experteer.com recommends that you make sure you can handle your workload and you're properly trained for new tasks, or you could be setting yourself up for failure.
Failing to listen
You may start a new job trying to show what you know, but don't dominate conversations, Time warns. Instead, listen to others, who can guide you with valuable input.
Talking about your previous employer
Think of your former employer as a previous boyfriend or girlfriend. Your current significant other doesn't want to be compared to your ex, and your present employer doesn't want to hear constant comparisons to your old company. You can mention things that worked at your former employer, but be helpful, not pushy, Experteer.com says.
Turning down invitations
Building bonds with your new colleagues is an important skill, so if you're invited to lunch, Bubble Jobs says you should take the opportunity. Otherwise, you could find that you're not asked again and will find yourself out of the loop.
Exaggerating your skills or experience
Don't act as if you know more than you do, Fast Company warns. Embellishing your skills and experience will come back to haunt you, so if you don't know something, own up to it and learn about it.
Dawn Zier, the CEO of Nutrisystem, told Fortune that learning the ins and outs of the whole company is important. You should make time to meet people in all departments and hit the ground running and working collaboratively. Don't be afraid to ask constructive questions, but make sure they're well thought-out and that you listen carefully to the answers.
Over- or under-sharing
You shouldn't share your entire life story with your colleagues, but you also don't want to talk only about work, according to The Muse. Strike the right balance between over-sharing and being too silent, which can make you harder to relate to and make you seem arrogant or aloof.
