Mitsogo Product UI/User Experience Designer interview questions

Considering most remain in COVID isolation, the whole process occurred online. the initial conversation occurred with their HR and she asked some generic things such as where I work, what I do, etc. After that, they requested to design a welcome screen for an iPad app and it wasn't a big deal because the only thing that we need to prepare is creating artwork for it. I designed one using a 3D application and the results obtained were excellent so I successfully passed that test. the final interview occurred with there lead designer. Like the HR, he asked some generic questions and asked me to explain the intentions behind the designs I prepared earlier. I assume that he wasn't happy about using a 3D program for creating it. My conclusion is that they were looking for persons who got some field experience and work conventionally.
