I was turn downed for a job offer after an onsite interview. This was sad news for me. What term could describe the brief sadness I experienced upon notification that I did not make the cut for a job offer? The key difference here is that I was upset, but now I am feeling better after some hours passed in this situation.
You felt dejected
unhappy, disappointed, or without hope:
She looked a bit dejected when they told her she didn't get the job.
I haven't come up with a single word but two similar idioms come to mind.
keep one's chin up,
to maintain a cheerful disposition in spite of difficulties, disappointments, etc.
take it on the chin, Informal.
to suffer defeat; fail completely.
to endure suffering or punishment.
On the second one, take it on the chin I know that term in a much more positive way.
take sthing on the chin at Collins Dictionary phrase [VERB inflects]
If you say that someone took something on the chin, you mean that they accepted an unpleasant or difficult situation bravely and without making a lot of fuss about it.
My sense is even more positive than the second.
to me, took it on the chin means more of the positive outlook a great athlete would have to be able to come back from a setback.
For lack of a better term for a very wide event concerning multiple stages of emotion from a negative stimulus, I'd say you feel bummed out or just bummed. This is, however, very colloquial and likely slang, however does convey the feeling that the dejection is temporary and only for some time, though only implicitly.
Consider using a more eloquent way of expressing this set of events, as it is essentially three separate events you're trying to encapsulate into a single word.
