Late last summer, I interviewed for a job with the same organization with which I did my grad-school internship. I didn't get the job, but I wound up getting the one I have now about six months later, so no big deal. Yesterday, completely out of the blue, I got a call from the woman who supervised me during my internship to let me know the position opened up again, and she encouraged me to apply (she's not the supervisor for the division that has the opening). Apparently, I was on the short list last time, so she feels like I'd be in great shape if I wanted to go for it again.
The job closes on Tuesday, so now I have to decide whether or not to go ahead and apply.
