Sounds like a disgraceful variant of others tactics to get pilots on the cheap to me. It's a shame that market conditions will no doubt ensure that it works and that they get the necessary numbers they need.
100 hours is no experience at all and to pay £25k for the privilege is insulting if there is no job guarantee at the end of it. It's a shame that Astreus do not have enough faith in their own selection process that they feel they have to pin all the risk on those applying.
Just another erosion in terms and conditions for pilots but hey we've been going down that river for years already.
Those who do pay and get a "full time job" as a result, best of luck to you but you will at some time regret it - I promise you that.
