I wouldn’t worry too much.
There is a regional shortage of A320 training capacity. So they are struggling to slot in training for new hires, plus upgrades. Plus the cyclic program.
You’re ranked on the hold file depending on your background. The ideal candidate is a Rex Captain. The acceptable candidate meets the mins. If the ideal candidate joins the hold. They will jump you for a start date. When the ideal candidates run out. They will start the acceptable candidate.
From what I’m hearing they can’t get enough or ‘any’ ideal candidates. There’s not enough to go around. So they are taking regional FOs. Single pilot multi engine guys and girls etc.
