I am working in this team since 2 years now as Graphic Designer & 3D Artist mainly for building visualization of architectural projects like residential buildings or office spaces etc.. The main challenge here was that it has been my first experience so far when i have worked under such large sized organization which had huge number employees within different divisions but still not able manage them well enough at times (mainly during project deadlines). But once you get familiarized then its really easy going around your colleagues/teammates there would always help if needed from time-to -time too! Its pretty good place where we can learn new things everyday about digital graphics designing process along other related topics also sometimes they will provide training classes regarding some specific software application / tools.
