The invitation to apply for CPH/HEL clearly states that all pilots are welcome to apply but must have a B737 rating even if expired.
Going back to the issue of direct employment, there is nobody employed directly by the mother ship but by fully owned subsidiaries. This enabled the company to bankrupt these subsidiaries in the countries where the cuts were made, and there was no preferential treatment for Scan based crews, neither the ARN nor the CPH based pilots received a single penny from the company, and had it been decided to bankrupt PSN, not even the Norway based pilots would have seen any money. As it stands at the moment, the only pilots employed are in Norway and Spain, and the dynamics of this situation have been covered here in detail.
