How was your first job interview? Any tips?

Tomorrow I'm going to my first ever job interview it's not that serious though. An English institute wants a 3rd or 4th year student to teach a pre junior class for two hours a week and they contacted our Eng department in our uni since they collaborate and so on. But still I know that there are another two girls who took interest and I kinda want to get it. The experience will be good, I'm interested in teaching, I'll be getting payed and I'll be able to substitute a lesson of mine for doing this. Do you remember your first interview? Any tips to make a good impression are welcome.

Thank you all who answered. I don't think I'll get the job. I was told about the needs of the class and I told them my aspirations but she asked me whether I'm a 3rd or 4th year student. She tells me that the other candidate has the advantage cause she is a 4th year student and she might want her to stay for the future as a part timer or as a full timer. So it's not that I did bad but I think she prefers a 4th year student over a 3rd year student.
