Be able to expand on any item on your resume. Review the job description and create your own list of skills. You may find it helpful to conduct an informational interview with someone who is currently working at or who has knowledge of the position. Use Hartwick's alumni connections, this is a great resource for this type of information. Once you have determined a list of appropriate skills, use your resume as a guide and check off things that you believe prepared you for the position.
Employers like to see concrete examples that show transferable skills.
If possible, prepare a portfolio of your best projects. Computer Science students also may find it helpful to prepare an online portfolio of programming projects which show a degree of proficiency with different languages. A word of caution though, use visual aids only as a supplement to your explanations, and only when it seems appropriate. Be familiar with the company's history, products, geographic locations and plans for growth. Learn if the company is a parent company of any subsidiaries.
