I applied through an employee referral. The process took 2 months. I interviewed at Oracle (Reston, VA) in July 2013
Interview
There were two 1 on 1 in person interviews and one phone interview. Most questions were directly off my resume wanting me to explain accomplishments, and just general questions about myself. I believe like any interview they were gaging your personality and your communication skills. Every interview was pretty standard and there was nothing that was unexpected.
I applied online. The process took 3 weeks. I interviewed at Oracle (Dublin, Dublin) in May 2017
Interview
2-3 HR interviews to scree the candiate followed by one or two interviews depending on how they like your profile. The first management interview is done by a tandem of managers to avoid bias, which is very good. If they both like you, you're hired (I think) and if one of the two don't like your profile it's up to another interview with the director.
