Girl gave me her number and I didn't ask for it, could she be interested in me or am I just leading to much into it?

I went to the bar a week ago and saw a group of girls and one that I knew so I went over and talked to them. One i really liked i talked to for a little bit but I had to go.

I happen to see her again the following week at the same place she was with some friends. We caught eyes and she kind of smiled and waved at me so I went over and said hi. She forgot my name but she remembered me so we started talking about what she does and im doing. Fully paying attention to me and playing with her hair. I've never had this happen to me before so i was getting nervous and couldnt think of what else to say so I brought one of her friends into the conversation. She told me her brother might have a job opening for me if I wanted his number too ask; I'm a recent grad. I said sure, than she said do you want my number too so I said sure. She goes out to have a cig after and I went out soon after to join said a few things, she gave me a hug and we parted ways.
I'm just not sure if she might be interested in me or just wanted to follow up with me about whether I may get the job.
If you think she is interested what should I do I'm very bad at this stuff and haven't been in a relationship in 4 years.

I'm 24 and she's two years older
