I have called before. “Hello, this is Jordym84 and I was calling to see if the position for CEO that I interviewed for on Nov. 1 has been filled yet?” You will get one of two answers. Yes, we have filled that position, which will let you move on and stop thinking about the job. Or no, we have not made a decision yet, in which you can say “I am still very interested in the position.” Trust me, they are not going to let dead air hang at that point. They will say something back to you and you take your cue from what they are saying.
