Good luck!

Dear Mr XXX,

Thank you very much for interviewing me. The XXX position is indeed challenging and rewarding. I am very much interested,

In terms of long hours during the close and budgeting, as we talked during the interview, it is not a problem for me at all. When needed, I work overtime at month end for my current job because it is my duty to close the book on time. ABC is a publicly traded company and they have a very tight schedule, just like XYZ.

I look forward to having your decision about the on-site visit.

Yours truly,

Me
