suppose that if you check their requirements on their recruitment website, and it doesn't say anything about having an unrestricted passport, then turn up to the assessment day. If they ask you a question on the assessment day about your passport issue, then just be honest and let them know.
Etihads website does not say anything about unrestricted passport.
But if I get the job offer and they do security check, won't they find this out anyways?
I don't think that on the assessment day they will know anything about my passport issue, since it's not the recruiters job to check our passports.
But if I have to fill out some paper work for them, and I'll stumble upon question about my passport, I'll be honest and just let them know about it. I'll wait and see.
