Before I got there, I saw on the website that the position is no longer available. So I figure they were just trying to get a candidate interview based on policy. The interview was like an exam, technical questions that are irrelevant to the position. My current job responsibilities were exactly the same as that on the posted site. When I got there, they weren't even ready to interview me. That moment I knew this will be wrong, and yes it went wrong plus I wasn't feeling too great. The hiring manager was questioning most of my skills of which I understand. They need to change the job title and responsibility in my opinion. The task is misleading to compare to what they are looking for. The interview was a joke.
