You were supposed to go on an interview in a few weeks, but you have since found out you cannot go on the date arranged.

I hope this letter finds you well.

Unfortunately, I have encountered an unexpected family emergency that requires my immediate attention around the time of the scheduled interview. This situation demands my presence and I must prioritize my family obligations at this time.

I kindly request to reschedule the interview to a later date that is convenient for you. I am very interested in the opportunity to interview for the position and would greatly appreciate your understanding and flexibility in accommodating this change.

I want to assure you that my interest in the position remains strong, and I am eager to discuss how my skills and experiences align with the requirements of the role. I believe that this role is a great fit for my qualifications and I am enthusiastic about the possibility of contributing to your team.

Thank you for your understanding and consideration. I look forward to the possibility of rescheduling the interview and discussing how I can contribute to your organization.
