As far as I know they don’t take low hours pilots. Usually Swedes are the only ones that do get it as low hours (no idea why, but could have something to do with the government funded scheme).
I was invited with low hours back in 2018, but already had a job at the time. Re applied again last autumn, now with hours on the A320 and heard nothing.
Good news is there will supposedly be a wave of retirements in the next few years (many old career FOs as well as normal captain retirement). They won’t be able to fill this gap with nationals alone, so SASI will need to expand or SAS mainline will need to accept international pilots.
