Applied to interaction designer role through their job portal with referral by a friend who's already working there. The UX team sent me a design exercise and promised a timely feedback on my design. I submitted a detailed design process, medium fidelity prototype and a design document. There were never feedback. I waited for 2-3 weeks and finally my friend reached out to HR, then HR sent me the rejection email directly. No words from the UX team whatsoever. I spent a lot of time finishing the exercise but they didn't even bother to reach back to me even they promised so. I mean, as a new grad, I know my approach to the question was probably amateurish in the eyes of their pros, but at least you could try to act polite by living up to your tiny promise.
