I would not go so far as to call it a recruiting freeze..... effectively to have a recruiting freeze you need to have had some recruitment in very recent times. The last course i am aware of was from an interview process done back in Feb/Mar with nothing since.
It could simply be that the recruiting porthole via staffcv is being overhauled, perhaps to include mins for EMB or data entry on the application for the EMB, i do not know i am just speculating. They may even be expanding the information on the application to include an outline of the recruiting process; similar to the info the other positions (cabin crew etc.) have. You never know, there may even be the introduction of psych and skill into the equation...........blah blah blah.
There is no end to the speculation that can be applied to the current sitution, i guess the moral of the story is we will just have to wait and see what happens; which will be nothing before the EBA is decided in any case.
Safe flying!
