I think they have recently opened up to applications again as they're advertising quite a lot on their Facebook page. There has also been a surge in Assessment days (Stage 2) with them having two dates every week!
As to the proccess, I'm not actually sure how long as there's people on here who have been waiting for 1+ years for their Stage 2 but also been newbies on here like me who applied end of January and already have a Stage 2 booked in for beginning of March.
Most of it seems like a guessing game with how long you have to wait but if you're interested then you should definitely go for it!! Good luck!!!
