I have recently applied for a job and I have received an email telling me that they had found someone already (so the problem was not my application, but the timing). Things like this happen, you have to expect it, but now I am wondering: how should I respond? I have written something but what is a no-no in this case? In other words, what can I say and what should I not say?
I'm obviously already excluding things like profanity or things like "it's your loss!", I am not talking about such things. In my case the answer is going to be absolutely positive and I have neither reason nor intention to express negative feelings.
For example, could I write that I might be available for similar positions in the same company or only for that specific one? If the second might be too restrictive (in general), the other one might make me look like "anything will do" which won't give a good impression.
