NCL POA Medical check

so I’m currently going through the NCL POA employment process and they e-mailed me a couple of weeks ago requesting further documents from my doctor. So I booked the appointment and faxed them the signed paperwork back but I haven’t heard anything from them about the rest of the process yet and I’m starting to get nervous.
What should I do? Will they let you know if they don’t want to further the employment process?

I’ve heard the hiring process there is a cluster of unbelievable proportions. What type of job are you going for? I thought the maritime jobs filled through union halls.
