Sometime we have to do something for the first time. You can face interview calmly. Do not make bogeyman of interviewer.
You appear to be fresher. Most of the time, for fresher job-knowledge related questions are asked. In addition to this, questions could be asked to check candidate's career consciousness. Interviewer might check the candidate's positive attitude or even attitude itself.
There are hundreds of questions that can be asked in the interview. Therefore, nothing is certain as to which question could be asked in your interview.
Prepare well and learn stress management techniques.
