I was trying to analyze a lot of such questions before our interview , unfortunately, I learnt one thing - the decision on our case was already made before we even walked into the interview. The officer wanted CIEP results. I don't think it makes sense for me to answer these questions of yours because , according to the officer, "both your profiles are positive and great, but I cannot accept your DELF results. Please send us your CIEP test results, atleast A2, and I will mail your CSQ". This is exactly what he said. I even asked if there is something I can do to improve our profile and send some documents. He said " As i said, you both are a young couple, capable of a bright professional career, speaking great english. I would want a CIEP test result to issue you a CSQ and I will give you 6 months".
Hope that helps!
