One telephonic Round, followed by face to face. The face to face interview was scheduled on a working day. They had two rounds stretching upto 1hr+ each and at the end of the interview, the feedback was positive. Also had a lengthy informal chat with the interviewer regarding the current work I am doing and also the work at oracle. They assured a callback by following week and told that I do not need to come down to the office for interview as the HR would be via telephone. And thats it. No feedback mails. No calls. No response to mails or calls. Just an abrupt irresponsible end for the full day effort you gave for the interview.

Round 1 DSA Asked a basic sliding window question and a few questions related to Java, like what are imaginary functions and then asked me a few questions based on my resume and then dived into technical aspects of it.
