You’re entering a period of intense learning and growth. But while you’re learning, you must also excel at your job. Here’s how to become part of the team as quickly as possible.

Starting a new job demands confidence. Don’t worry if you have doubts. Just keep them to yourself and appear as confident as possible to others. Part of demonstrating confidence is looking the part.

So dress your very best for your first day. Also, make sure to arrive early. If you’re traveling a new route, by car or mass transit, leave time for contingencies.

Now, when you arrive, remember that first impressions are very important. So walk in with a smile on your face, a bounce to your step, and your eyes ready to make contact.

When you meet people, be polite and friendly and be sure to give firm handshakes. Try to remember names as best you can.

In your initial conversations, take note of people’s responsibilities. Feel free to ask them questions about what they do. If you’re not sure of something, ask. People usually will be more than willing to help.

During your first week and months on the job, don’t challenge the way people do things. And never, ever utter the words, “That’s not how we did it where I used to work.” You don’t want them to think, “Well, why don’t you go back there?”

Other tips for adjusting to your new job:

• Ask questions. You’re better off asking someone for help than doing something wrong and having to re-do your work.
• Let people get to know you and try to get to know others.
• Use your lunch and coffee breaks to bond with your colleagues. Limit lunches with those at your old job; they represent the past. Your new colleagues represent the future.
• Make sure people who give you assignments have the authority to do so.
• Uncover who has influence, both officially and unofficially.
• Listen to the grapevine, but don't contribute to it. You don't want people to think you’re a gossip monger.
• Don't say negative things about your boss or your co-workers.
• Come to work early and stay a little late, if possible.
• Be open to projects or people needing help. But don’t neglect your current assignments.
• Remain open-minded. You’re an employee now, not a candidate. So you will see the negatives as well as the positives about your new job and employer. Be patient while a well-rounded picture emerges.
