You should be proficient in the fundamentals of programming languages (in which you are good), OS, and networking.

There will be two technical rounds:

• The first technical round is manageable but difficult to qualify for.
• The second round is difficult, but if you pass the first, it's not a significant hurdle.

There will also be one HR round, where you can almost confirm your entry into Oracle.

(*Make sure to include some very good projects on your resume.)
