How to cope with a situation, when I withdrew from a job search, but now I regret it?
Two weeks sounds like a lot of time and it is likely the position was already offered to another candidate. If it was, you lose nothing by sending an email. If it was not, they probably do not have an appointable candidate and in this case they can be actually quite happy to offer the position to you. However, consider providing a brief explanation of why you have withdrawn and why you are now asking to reconsider you for the post. The appointing committee needs some reassurance that you will take the post if you are offered it.
