TORC Robotics Software Developer - Behaviors Interview Interview interview questions

Applied Online. Sent 2 hacker rank coding test (one - 2 hours, one technical questions ) (2 weeks deadline). In CodePair video interview asking about c++ fundamentals and background. When I asked technical questions I got rude reply "you are not here to evaluate us". Well why would anyone wants to work for you, if you can't even answer simple questions. Interviewing a candidate is a 2 way communication. If you are evaluating a candidate by asking him about his background to see if he will fits in the role, then be ready to answer his questions. he has the right to know what he will be working on. If you are so concerned to discuss about the details, can you simply say we can't say more without signing NDA. I am giving a negative review because of this.
