I can't advise strongly enough against this outfit.
CityJet used to employ only through their cadet scheme or by taking on experienced pilots. They also used to pay for their pilots type ratings because the RJ is an old aircraft, few airlines use them anymore and so the type rating is all but useless.
However, because they are struggling so badly they are now pairing up with simtech to charge for assessments and for type ratings, because they know new pilots desperate for jobs are willing to do anything to get the foot in the door.
If you're willing to fork out for a type rating, go to Ryanair or EasyJet or Aer Lingus anywhere else where you will get a decent rating and at least get a semi decent salary.
The reason CityJet are offering these assessments is because they are desperate for pilots because all their current ones are desperately jumping ship and getting out because the airline is struggling, the management treat them appallingly, and it isn't a remotely decent place to work anyoure.
Second officer starting salary is less than €25,000.
Honestly, I'd reccomend steering clear and trying for the likes of Ryanair - you get a decent rating, it's good hours and pay and after a few years you can look at moving on to bigger better places.
