Hey guys just got back from my interview in White Plains. I still haven't heard back yet but I think all went well. Its definitely a suit and tie event in case you were trying to figure that out. Read up on NAT and SLOP and be prepared for questions about loss of pressurization on NAT routes as they were common questions. Also there could be a lost comms question on a STAR, before you rattle off the lost comms procedure make sure it isn't depicted in text on the chart he shows you.
Some other questions involve holding speeds, when you can continue an approach in England in bad weather (apparently its different) can VMCG be higher than V1? There were a fair number of questions involving RVR so study up on that as well. Other than that its not too bad. They are all pretty laid back and I think they mostly want to see if they could fly with you for 20 days straight. Hope this helps PM me if you have any questions.
