I was technical interview round. First of all they gave us a form in which we had to fill details like 3 technical skills and their rating, 3 favorite movies and books, 3 weakness, most embarrassing moment in life and strength and weakness.
Then I was called for interview. First he asked me about myself. Then asked java questions related to function overriding and overloading. Then he asked a puzzle. That was like if I have boarding passes of a person without date and time and only with source and destination. If I shuffle the cards, Is it possible to tell the first initial source. I said no without time and date it was not possible. Then he played around this question for sometime. Then he asked the standard problem :- Count the number of islands in a Boolean matrix. I gave the dfs solution. He was satisfied. Then he asked another puzzle :- Given 4 pages and written with x, y, 1, 2 and I have to make the minimum flips to make the pair(y, 2). (Very confusing puzzle). I was able to answer a little, not much. Then I had projects on Android. He asked few questions about my project and I gave him right answers.
