Honestly you have to consider the risks you take by accepting a TR course in March. Some contractors at Buzz are not payed because they don't fly, other pilots are on unpaid leave this winter, and they fly no more than a few sectors a month otherwise. Ask yourselves the question : Do you really expect them to need more pilots in May ? Things have changed since 2019 when they last hired : you are now applying for a training course and not for a job, be aware of that. It will benefit the airline and the airline only : they need some cash right now, they have training facilities, why not sell Type Ratings to some people ? If they finally need some pilots in a year or two, they might call you (or call the latest guys who have finished the TR and just forget about you), otherwise you'll just go away with your brand new TR trying to find an other job. That's all. They will not guarantee any job.
Let's pretend recruitments are actually on the way up (they are not, let's just pretend for a few seconds), then it's only the beginning for Ryanair to hire and there is no rush. Just wait a few months and see how's the summer going. There is no job at the moment because no one is travelling and fleets are grounded. It's the hard truth but you have to live with that. If someone is hiring, then there's something not clear going on.
