Cognizant Software Engineer Associate interview questions

I applied on campus here. There were 5 rounds. First round was an online test having aptitude and 2 coding questions. Ones who has done a single question is selected for further process. Second round was a coding round. There was 4 coding questions needs to be solved in 1 hour and 15 minutes. Third round was technical interview round. Initially they asked me about my projects. I explained to them for about half an hour. They were quite impressed with it. They also asked me some sql queries and also some programming terms. Fourth round was also a technical round. They asked my strong language (JAVA) and asked questions related to it. They also asked me some hard sql queries which I couldn't answer. Also they asked me some puzzles. Fifth round was HR round where they asked me about my personal information. Also they asked me if I want to work in a specific city. Always say no, else they will not allot you the projects if they have on different locations. Also they asked if I can work on some Saturdays (if needed), I said yes. They selected me.

first was the technical round they asked basic concepts from dbms ,oops concept and description of final year project.people who cleared the technical round went for the hr round.hr round was very relaxing not much questions.All the student cs and it students who cleared the technical round got selected and for others hr did matter
