The interviewers were friendly and easy to talk to. They would remind you that it is okay to not know an answer and gave time to process teir questions. Some questions were asked in a stern manner that would make you think "oh god I need to know this but I don't". What I soon realised was it was quite the opposite. After my reply they would even say they do not know the answer themselves, but wanted to see if I do and more importantly, if I would try to create an answer or just be honest and tell the truth, maybe even explain how I would find out or go about the problem in general. I think the interview was amazing and the interviewers did their Job very effecively.
