I had a couple of interviews, the first with two Research Directors who would be the team leads. The second with the head of division. Both were easy flowing conversations, neither was at all a grilling. They were more focussed on me showing intelligence and being interesting than asking "what do you do on a daily basis". They were very transparent about what they were trying to do with the division and we discussed what i wanted out of the role, including progression opportunities. The head of division was able to sketch out a roadmap for promotion in the interview for me. And then later confirmed the steps and dates involved in the offer letter he wrote.
