Royal Cyber Inc. J2EE Developer interview questions

This company found me through my university's online recruiting database, and frankly were expecting someone with workplace experience in J2EE development, which obviously as a student I did not have. There were some relatively simple questions such as the difference between an interface and an abstract class, and one that completely threw me off: the difference between a facade and flyweight model. I had never even heard of that before--and it got worse from there.
