Yes, I got a stage 3 invite shortly after I posted saying I expect they've put everything on hold
I am going to take a pragmatic approach as well, go for the interview and then if I am successful make a decision later down the road. Seems pointless not going for the interview as won't loose anything at this stage apart from a days leave from work and cost of travel etc. I am in the fortunate position that I already have another career in the public sector with a very secure job but and, although a pilot career is what I aspire to, I feel more sorry for those that don't have alternative options or are committed to this being their only option.
