Thank you for your letter on April 17. After careful consideration I regret to inform you that I am unable to accept your refusal to offer me employment with your firm.
This year I have been particularly fortunate in receiving an unusually large number of rejection letters. With such a varied and promising field of candidates it is impossible for me to accept all refusals.
Despite your outstanding qualifications and previous experience in rejecting applicants, I find that your rejection does not meet with my needs at this time. Therefore, I will initiate employment with your firm immediately following graduation. I look forward to seeing you then.
Best of luck in rejecting future candidates.
[Your name here]
