Each company will be looking for a different set of qualifications for their internship. To match the expectations for any given posting, you should use keywords from the job description in your resume.
Tailoring Your Skills Section
We strongly discourage adding skills you have no experience with to your resume just because they appear in the job description. However, it's ok to add skills that you aren't an expert on. If asked about them during an interview, you can always say that you only worked with the software/concept once and are eager to earn more.
Adding those extra matching skills to your resume may help your resume stand out and get you a first-round interview, which is the hardest step on your way to an offer.
