The interview process was multi-stage. The first stage was an initial meeting (virtual), the second stage was a research task and presentation, I withdrew from the process after this stage but I believe the next was the final stage.

Unpleasant interview with direct line manager. He cut me off twice and said 'this is not what I'm asking', and when he disagreed with my perspective, he said 'I disagree with what you said, you are wrong, but FINE', doesn't feel like being treated respectfully and can already sense the culture is not open at all when you look at the line manager's behaviors
