Wayfair Supply Chain Associate (German) interview questions

Contacted by e-mail and invited for an interview. Nice working environment that you can feel once you step in to the office. I was interviewed by a very young person, didn't feel that she was professional at all. Questions were easy and typical.describe a time when you had to work in a team/describe a failure. At one point she said we should switch to german so just proceeded with the interview in german.
