The facts are:
If you have 1500+ hrs including 500 jet or 1000 turbine then you are regarded as 1st Officer grade and the starting salary is £36,681
There are various second officer grades for people with less than this and the pay for second officers starts at:
Second Officer 1 £24,970
Second Officer 2 £28,538
Second Officer 3 £32.105
The formula for the ranks is quite complex, well, too complex for me to type out!.
After my discussion with them I got the impression they were looking for people with jet or heavy TP time, but like many airlines cast a wide net to keep the demographics correct. Having said that, one may assume the number of entry level jobs would be limited as there are a few guys around with the requirements at the moment.
The overall package works out less than a FO with time at Ryanair.
Good Luck
