Oracle Developer interview questions

Hiring process is through college. Once you crack an aptitude round, they calls you for an interview having 3 rounds. 2 technical and one HR. Cracking Oracle aptitudeis very difficult. But existing question papers on google helps a lot.

One phone screen with engineering manager, and two rounds of in person interviews. Was asked to provide code samples of some of my earlier projects. The interview rounds were fairly mixed, all with the exception of the manager's interview were technical. Question focus was on graphs, lists and general logic.
