Letter: Dear XXXXXXXX:
I enjoyed meeting with you during my recent visit to XXXXX University. I was impressed with your personal and professional qualifications.
Unfortunately, due to the staffing requirements, we can employ only a limited number of the many candidates interested in our firm. Even though we are unable to offer you an internship position, we are impressed with your qualifications. I would like to keep in touch as you continue your education to further discuss full-time career opportunities at Ernst & Young.
Please accept my thanks for participating in the interview. Good luck during the rest of the semester. I look forward to seeing you again in the near future.
