1st round completely hands on modelling and queries, 2nd round interviewer came with use case(a half cooked) to solve/write as a query or code but told no need to be accurate but give me logic to solve the problem, I provided in a rough query and a pseudo code but after that no response,, even I tried to complete the query and sent a snapshot.. I felt a bit unprofessional... if I am wrong they could have told me what is wrong.. for every problem there will n no.of sol in software, i think it is waste of time with Oracle(such a big company) but no professional process of recruitment.
