"I'm here for an interview" is fine.Originally Posted by jack
"I'm here for the interview" works if you know that the person you are speaking to knows about the appointment, and knows who you are.
"Hello Mr. Smith. I'm Jack. I'm here for the interview."
3 is fine. 4 is quite wrong. You should use 'the' because there is only one store in the situation (the store where you will have the interview), and we can infer that from your first sentence.*About the sentence above, which one do I use? How do I know which one to use? Are these correct?
3. Now I'm am at the store, do I say:
4. Now I'm am at an store, do I say:
But even if you were going to use an indefinite article with 'store' in another context, it would be 'a', not 'an'.
5 is correct. 6 is grammatically incorrect. "Which one do I use" is colloquial, and with "How do I know", it sounds like too many "do I's" for such a short sentence!Also, are these synonymous?
5. How do I know which one to use?
6. How do I know which one do I use?
