Summarize this article:

Try to make your volunteer work essential to your supervisors and coworkers. You want them to feel that you have become a necessary part of the organization at the end of your volunteer work. Do work that matters and avoid the easier work whenever possible. This will demonstrate your value to the company as someone who is willing to tackle the hard stuff. Try to find tasks that only you know how to do so that the company relies on you to complete them. Learn a new skill that they need someone to perform at the company, such as speaking another language or how to code. Tell people at the organization that you would be interested in working for them when your time as a volunteer is up. This will help make sure that they keep you in mind for future opportunities, even if there are none available at the moment. Check the organization's online job postings for paid jobs to apply for. Ask the recruiting department about opportunities and be the first to apply. This is where those achievements you tracked as a volunteer come in handy! Make sure to put all the skills you learned and any quantifiable successes on your resume and in your job applications. Let your supervisor at the organization know that you submitted an application for a job. This will help put you at the top of the list of applicants. Even if there are no jobs posted at the organization, you can still talk to your connections about opportunities and perhaps you will open a door or they will contact you when there are jobs available.

Summary:
Become indispensable to the organization in order to grow with it. Let the organization know that you are interested in a paid position. Look at the organization's job postings and apply to any that are relevant. Speak to the connections you made about job opportunities and applications.
