Has anyone here applied for a schengen visa for a family member?

I'm a non-EU family member (spouse) of a Romanian citizen. I'm wondering if anyone here has experience applying for schengen visa inside Romania for a non-EU family member? Asking because I'm afraid the usual bureaucracy or that they may ask something that is not even necessary to the application.

We've secured a schedule for a Schengen visa application in the German embassy in Bucharest. We already know that you can travel together by land (as we've did last year, going from Arad to Budapest and then to Vienna and Hamburg), but we are sick of long and expensive train rides and would rather fly from Timisoara out. We were wondering if they would need things like flight ticket reservations or hotel reservations. I know they shouldn't as we are activating my Romanian husband's right to travel- and we are staying with friends so we do not have hotel reservations, and they are not supposed to ask for employment papers, bank statements and invitation letter/ hotel reservations. But we are afraid of what if's- if they ask for these documents, since we are going from Arad to Bucharest and that's a good 11 hours overnight on the train and it would be a nightmare if we'd go there and they'd ask unnecessary things- we're just used to Romanian bureaucracy so we expect something going wrong

Hope someone can share their experience!
