Thank you doriswe. I think it went pretty well. It was just my director so I was not as nervous. Her reactions to my answers seemed good so I think I "passed", lol. I brought some backup for my answer as well.
She has more interviews schedule for the next week or so and then she said they'll mode on to 2nd interviews. The 2nd interview will include more people though, so I'm sure I'll be nervous then. ETA: if I make it to the 2nd interview.
