Selection of candidates for PPO was based on the work they had done in internship, manager review, and on the final interview . My interview was majorly on DS-Algo but my friends were asked questions on java, OOP , OS, DBMS, even Computer Networks. Design question was asked to almost all of us. Two years back, the interview used to be of 3 rounds which tested everything you know. But they have changed the format and I guess more weightage is given to the project work and manager review. But yes interview does matter. Questions asked in the interview depends on the interviewer (each interviewer has a particular set of questions) and also on the technologies you have used in your project.
