BONUS opportunity--take note of the points I posted in the cover letter announcement and improve your cover letter. Now use it as a basis to draft an email to this potential employer and attach your resume. In this email draft, include a reference name of a professional that would be of interest to this person. For example, a professor in your major has provided a contact name at this company and suggested you send this specific person your resume. Your professor has given you permission to use his/her name in your email (always ask to be sure that you can use someone's name like this). Make sure you give the employer a reason to open your resume and contact you for an interview.
Just write me the cover letter as you are an operation managment major seeking a job in apple.
