When you get a new job, everything about the job is going to be new to you. A new company that you will be working at, you will have a new manager, you will be working with a new team, and you will be meeting new people at the office. This is a very exciting time when you move onto something new in your career but this it is also a time when what you say and what you do on your first day of the new job will be noticed by everyone.
Everyone will be sizing you up on your first day to see how you fit into their work environment and how you will affect their work life. This is all very natural and part of the dynamics that make us human. This is especially amplified when you put this into a work environment where people need to compete to move up in their careers. People want to make sure that you do not represent an obstacle in their career growth and upward mobility to move into bigger positions. If people see you as a threat then they will not be very friendly to you at all. In fact, they may be strategizing ways in making your position ineffective.
This is why first impressions are very important when you meet new people in a new work environment. You want people not to be afraid of you but to accept you because you will help them make their lives easier by providing excellent service to the client. You should also let them know that you are new to the organization and that you are looking to learn from the people that have been working in the organization. You have the opportunity to come off as someone that wants to learn new things, is very approachable, and friendly.
When you meet your new boss, you want to show them that they indeed made the right hire. You need to demonstrate that you are an expert in your knowledge domain and that you can be a solid foundation for their program. You only get one time to make a first impression, so please make it count. If you make a negative first impression then you are going to have to work that much harder to change perceptions. Do not worry if this is the case at your new job because you can change the way people feel about you.
