One of the meanings of 4 of wands is 'home', so perhaps the card was implying that you'll stay at home, hence you'll not get the job. Does that apply in your case?
I started to see this card a lot once I quit my job and was forced to spend most of the time at home. I think it also might suggest a period when you need to get some rest, because there's nothing else you can do at the moment.
This is the answer I'd lean toward, too.
Do you use reversed cards? If you don't, then this could be a card to read reversed in this reading in my opinion.
