Group job interview -help!

I applied for a job today and met the boss, and she told me that they have one more job opening left and there is another girl who has also applied. She informed me that I would be in a group interview with her on Monday. Does anyone have any tips on group job interviews?? I really need this job. I’m in college and hurting for money. I will be applying to other places as well, but this is a convenient job for me.
