Oracle Senior Developer interview questions

The telephonic round was mainly core java and some design on a virtual case. 1:1 interview consisted of 3 rounds. Tech Lead, Architect and Manager round before the HR. Tech Lead Round was based on Core Java combined with J2EE dealing only with concepts.. SCJP tutorial is enough for the same. Architect round was only on data structures and coding based on some given problem. Manager round was on completely on designing and further questions depending on what you design.
