DTT Multimedia UI/User Experience Design interview questions

First, DTT sent me an email and give me several general questions about myself. After gave the answers, I proceed to the test. I am given a test with professional standard brief that I found quite challenging for me, but giving me more understanding towards DTT standard product. After that, the DTT team looked up to my test result and approved it, so I got an invitation to do an interview in the office in Amsterdam. Then, we have some discussion and I got accepted.
