Wipro Software Developer interview questions

1st round was aptitude test,which consisted of english,basic maths and reasoning. After clearing the aptitude test,there was a coding round. They said that they'll announce the results after 10days..But,they ended up announcing those one day before the interview. That was very unprofessional. The next round was Technical interview. I told the interviewer about myself,told her some programming languages i was familiar with.. I answered and could not answer some her questions.Also,she kept asking about Database Management.I could answer as i had no idea about that,and i got rejected. I guess if had prepared that i would have been selected for the HR round.
