Oracle Developer interview questions

Applied through careers website. I was contacted by an email thereafter by a short phone screen by the Project Manager. He scheduled 2 technical phone interviews in the following 2 weeks. First interview consisted of designing an application - identifying the functional requirements and justifying the tools I would use to implement them. I was also asked 3 puzzle problems and 1 coding problem. They were difficult but the Interviewer guided me to the correct solution, unlike other interviews I have given in the past. Second interview consisted of questions related to my career goals and described about the project's requirements. Both the interviewers and the Project Manager were extremely polite and forthcoming. Alas, I wasn't selected as they found better candidates than me. Being a college grad is tough.
