Does the withdrawal of sci papers have a big impact?
If you are hired, the impact will be considerable, and if you are not hired, the impact will be smaller. Unless the results can't be copied or there are academic moral problems, you can't just withdraw the manuscript. This is a concrete influence with legal effect. It depends on the reason for the retraction. For example, the consequences of fraud will be very serious, but there are also honest mistakes that lead to the withdrawal of the manuscript.
