Hi Daniel,
The 6 month contract is a 'Training Contract' that is issued to cover the Base Training & Line Training period. Upon successful completion of this, cadets will move to a more permanent contract with Ryanair or a Ryanair Group airline. The reason we do not outright offer job guarantees because it is dependent on each cadet successfully completing these training elements. This has been the same model since 2018 and to date we have had a 99% success rate of cadets at this stage and all successful have moved to Second Officer / permanent contracts. As will our first cadets of 2021, scheduled to complete the Line Training in the next few weeks.
If you have more specific questions regarding this you should contact the MCC provider who can relay these questions to ourselves as one of the major benefits of the Ryanair Mentored Programme is that you get a direct link to Ryanair Flight Operations and Recruitment while on a Mentored course.
Thanks
