Dear Sir/Madam,
I am Riccardo Marciano and I have recently passed a job interview for the Software Engineer position at the Software Infrastructure group. I was expected to start on November 15, as agreed, and am writing because, unfortunately, I will not be able to present myself on that date.

Sincerely,
Riccardo Marciano
