Got an Android Interview with Discovery Inc.

Hey people, I have an Android developer interview coming up with Discovery Inc. I wanted to ask if any of you people have experienced the interviews for an Android/Mobile developer at Discovery. How was, how were the questions. I am specially concerned about the Design round. Will it be a traditional system design interview (building backend/infrastructure for an app) or will be an app based design interview(building an architecture for a mobile app). Also, any tips on the behavioral rounds? Please let me know. #interview #systemdesign #android #mobile
