Infosys Software Engineer Java Developer interview questions

1st round was technical. It was a drive where recruitment for various technologies was going on, total of 700 people came. Waitinf time was not much but the interviewer was really unprofessional. Yawing all the time and saying "excuse me". Started with core java and went up to framework level. The interviewer was not understanding the answers given my me. Whether it was about HashMap or Spring. Also he asked me about frameworks and told me to explain the architecture of the project. Also asked about procedures and triggers. The projects are really outdated and there is not much scope of learning as he described about the projects.
