Loganair
Let me state the obvious.
If you stuggle to obtain your CPL/IR by requiring additional training/testing then you may be classified as a "training risk".
Sometimes airlines assessment teams take a risk themselves, and select a FO who may be considered to be a marginal training risk. Sometimes it works out - sometimes it does not.
If you do not fall into this category, then provided you continue to put in 100% effort to your type and line training you will succeed.
Loganair is an excellent training platform for those early years to develop your skills. With an ATPL issued, you are ideally placed for that first jet job having had an enjoyable time on the Saab.
NDB into Islay on a dark windy wet night is a good introduction for those Greek Islands at night !!
I think ACA [the previous posting] will bear this out in his 757.
