请教什么叫做“the date she was notified of this employment posting”

这个版面高人很多，把帖子发在这里求教，请版主见谅！

收到一封信，原文如下：

Please confirm the commencement date of her employment with xxx company and the date she was notified of this employment posting.

不太明白信中“the date she was notified of this employment posting”这句话的意思，请高人指教，谢谢了！

她是哪一天被告知已经被公司录取了。。。
