A special task with regard to filling specialist and management positions arises when subsidiaries from corporate groups are sold. Often qualified managers want to remain in the group and can also demand this, so that the need arises to close this gap. Since the selection should better be made by the new shareholder, but he cannot yet act officially, there are solutions with interim managers. The format is also conceivable that managers are initially in an interim status, but can then switch to a permanent position if they prove themselves.
