The moment you decide your passion or field of interest it is important to become knowledgeable in that area.
You should start off by attending internal organizations or groups in order to easily connect with colleagues who work on a similar team or interacts with your team in some capacity.
Next, think about how you will approach assignments or tasks that will be assigned to you; what questions to ask in order to get quickly up to speed.
1. Identify where a history of artifacts are stored so that you have a copy of templates and examples of documents to leverage when asked to complete a project or task.
2. Meet with your team members right away, explore meet and greets in order to build relationships.
As you are assigned projects, no matter the industry: customer support, education, marketing, consulting, science, always pay attention and take notes and identify areas that can be improved. Once you begin building experience within a single company or others, you'll begin building a name for yourself.
Others will identify you for your specialized skill and call upon you for assistance within that area. That is how you build a brand, becoming known for a particular skill and need that someone needs fulfilled. Your brand is your skill, the value you bring to a team or company. It's important to always nurture your brand, and consider the "what" of what you want to be known for in your career.
