Oracle came to my campus for recruitment. The first round consisted of aptitude and simple questions related to computer science engineering curriculum. The next round was a combination of technical and HR interviews with rolling rejections. The purpose of these interviews was to check fitness for work culture, determination and focus. They looked for confident students with ambition. I was asked to take part in role play in which I had a stay up idea and approached a venture capitalist for money. I had to give convincing arguments and not lose hope when I didn't know some financial details.
