Answered about the BK of the company and that it was due to ownership transition, not sales (as I understand). I didn't like talking about it because those people weren't there to defend themselves and I think the interview sensed that and did not push deeper.
This is a summer-temporary position, but there may be a couple full time, benefit-eligible positions open at the end of the summer. What makes you different than the last applicant and why should we extend your employment after the summer?
I highlighted my customer service experience and made sure to mention how I deal with stressful situations or irate customers. I reiterated my love of music, how I wanted to show others how to make music, and just kept calm. Again, customer service is critical to this position. If you get this question, make sure you highlight your experience and ability to adapt to changing priorities (i.e. on-call shifts).
Breathe. Always remember to breathe and remember that hard work and dedication with get you where you need to be. Just breathe, take a walk, and let positive energy fill up your lungs when you take a deep breath.
