1. Confidence is key: show that you believe in yourself! Justify your desired salary with the qualifications you bring.
2. Do your research: Make sure you do market research on the role and what other companies are paying interns/new grads for the same role in your location. 
3. If you are interviewing elsewhere and have been offered a higher salary than what you are given at [Company Name], use that as leverage when negotiating your salary. 
4. It is important to maintain professionalism and politeness during negotiations, regardless of whether you reach an agreement. 

Script you can use (modify based on the skillsets you want to highlight): 

“I am so honored to be joining the team. I have truly enjoyed my interactions with everyone during the interview process. Is there any chance of flexibility in the salary offer? Based on a few additional conversations I am having, market research, as well as the experience I am bringing as a new grad with 3 years of experience building and launching iOS apps from the ground up since my first internship my sophomore year of college, I would love it if we could potentially meet at $[Desired Amount].”

Negotiating your salary as an intern or new grad is a great opportunity to learn how to advocate for yourself which is something you will encounter many times throughout your career!
