Interested in Language
How could I write a letter to the employer asking that to know status of the Interview attended on last month.
Welcome to the forum.
Write what you would say to the person if you were talking on the phone.
Post that here and someone will take a look.
Note that I am moving this thread to the "application" section of the forum.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
