The interview went well. I had to attend the interview at the Infosys Coimbatore branch.. Having basic knowledge of DSA and SQL helped me a lot. I was also asked to solve pattern printing problems, like writing code for a chessboard. The HR was very kind and made me feel comfortable, which helped me answer all the questions confidently
