Infosys Developer interview questions

initial offline coding test and then after clearing that was called for live coding test and asked to write a java program and after clearing this i was told there will be an technical interview followed by HR interview

The interviewer was very serious looking. First he asked me whether I had lunch or not and some other questions to lighten the mood. Then he asked me to give my introduction from which he pointed out my favorite topic DBMS and asked about images in database, that how can we do so and if it is efficient or not. Then some other simple C questions and finally a program for a triangle pattern in C.
