This was my first interview ever, they called to invite me for an interview on the same day that I had applied, which was a pleasant surprise. They said it was relaxed, so I can dress casual, but I ended up dressing a bit formally anyway. The interview was with 2 employees, one of them would ask me questions and the other would write down my answers. I think it went pretty well, they were really nice and talkative (they would sometimes elaborate on what I had mentioned by sharing their own experiences). They ended up calling me back about a week later, I didn't get the job, they said the interview went well but they had more experienced candidates (which was quite heartbreaking).
