Dear Sir/Madam,

Sample Answer Letter Of Request (Formal Letter).

Dear Sir/Madam,

I am writing this letter to request a change of date for my interview upcoming with your company.

It saddens me to make this request because I have been looking forward to this interview but my grandfather passed away and a family gathering has been fixed for the same day as the interview. The gathering will be taking place at my grandfather’s house in Chennai, making it difficult for me to attend the interview since it will take hold in Agra. I was also informed that all members of the family must be present at the gathering, hence I won’t be able to make the interview.

My scheduled interview is on the 30th of April. If it’s not too much to ask, I would like to request that it will be changed to the first Friday in May that will be on the 7th. Another day can be fixed if the 7th of May won’t work for you.

It has been my dream to work at your reputable company and I will be delighted if given a chance there. So I am still very much interested in taking the interview.

I will be looking forward to your response.

Yours Faithfully,
Alestairsimon
