Please don't even bother giving an interview at this company. They ask a question to design one of the use cases of their system. And the answer they want is exactly how their system is currently designed. Since as an interviewee you think from a fresh perspective and provide them suggestions, then they outright reject it. If you find fault in the approach they are suggesting, then they get offended and take it on their ego. They simply want you to come up with the exact same design they have implemented currently, and they want you to tell them that it is correct; otherwise, you are rejected.

Questions about the current project. Questions about system design.
