Getting a second interview what does that mean?

I went in yesterday for a job interview at Ross and at the end the lady told me if I can make it for a second interview with some other person that will be interviewing me on Tuesday I told her it was no problem. What does it mean when they ask you for a second interview? I don't know if I did all that too well my nerves were taking over and every time she asked a question to give her an example of a so and so time I felt like my brain was freezing on me (yikes) =/ I am always a nervous wreck when it comes to job interviews. I've had quite a few job interviews in the past this is the first time I get offered a second job interview. I guess that's a good thing? Also, 1 day before my Ross interview I had an interview at Burger King it went okay with this one but the lady had other people coming after me to interview also for the job. She said by Thursday(today) she was going to be making calls for the job. I'm waiting for the call it's still early, if I don't receive the call at the end of the day should I call tomorrow and do a follow up? If I get offered both jobs which would be best to take? I have both pros and cons for both jobs one of them being location Burger King is super close to my house and the other being one is a retail store and the other is a fast food restaurant I think working in a retail store would be more fun that at a fast food place. What do you guys think?



P.S. i post this twice but it's because no one answers my questions :b lolGetting a second interview what does that mean?
Means you better step it up if you really want the job but you better decide it might be a little hard trying to juggle two jobs at once
