IBM Asociates Software Engineer interview questions

Interview at my campus 2 rounds 1)written(series questions) platform was not at all good .. be careful while appearing.. totally concentrate on series problems 2)single interview where your confidence is tested rather than your answers.. I told him many wrong answers confidently....even though got selected. he asked me about AI we had a long debate where I was really confident which made me to impress him. he asked me which one is faster ?? java or c?? I don't know the answer so I just said java and gave some explanation confidently

It was a pool campus in Pune. Around 200 students participated. The first round was aptitude where the timer was for every question.You cannot go back to the same question once you move ahead.If you pass the first test you can attend the next test which is business communication test. After that you are selected for interview.
