There was a written aptitude test in that Last 5-6 qns were SQL qns. About 20 appeared for the interview and I ended up being 1st after the test. They eliminated about 5 candidates after the test.
Interview was really easy. He just asked some questions related to data structures. Interview began in English. Later he started talking to me in malayalam. He also told me that the company mainly uses ruby on rails and he was selected as Android developer but never did any Android related stuff in the company.
