What other people's experiences are here really won't give you any insight in this case. Submit the contract and see what comes of it. In an emergency, there are still other banks you can contact – that shouldn't be a problem, right? A fixed-term contract apparently isn't an obstacle anymore. By the way, my husband was on probation. But no one asked about that afterwards, nor about the contract (although it was permanent, they didn't know that either). For us, for example, they only asked since when one has been employed where, and we answered that truthfully; that was ING.
Good luck!
