I applied in-person. The process took 3 weeks. I interviewed at Oracle (Seattle, WA) in Jan 2010
Interview
the interview process did involve a lot of questions and also a lot of phone screens and then an onsite interview which meant flying to a location of where a partner lived in their state and you had to meet up with them for a cup of coffee. overall it wasnt bad
2 rounds of technical - They will ask all the technical questions based on your resume. Quite difficult
1 Manager Round - They will ask technical questions and managerial questions
There was 2 technical interview and one managerial round. L1 round was with some Java coding using stream and theoretical questions and L2 round was more about the scenario based questions
Interview mostly they will ask the basics but from each and every topic for Oracle DBA like configuration, architecture, RMAN, EXP/IMP, Performance Tuning, RAC, Golden Gate, Exadata and Cloud platform question etc.
