To be fair at least they will be providing hotel. I believe its £3 train to didsbury from airport so not going to bankrupt anyone.
Check out the Jet2 thread, they want you to pay for rating, accommodation whilst doing said rating, 50% pay until line check completion and then all you have is a 70% contract.
It is ridiculous to think they will pay for transport to the interview, would you expect the same from any other industry???
