We don't grade Staff Applications based off grammar and use of vocabulary, so not sure why you'd try to compare this to an English course?
Plain and simple, you lacked detail in certain areas that we were expecting more from. If you want this to be explained in more depth, you can DM me or any other staff member and we could explain that to you. Making a public thread about it is just another reason that goes to show this. Also, yes, we have not recruited anyone yet because the Applications are still open!
