Initial interview was great, informal, get to know you type scenario. 2nd stage interview onsite was not. It felt more like an interrogation, there was an exercise which I hadn't been asked to prepare for - despite asking if I needed to prep anything for the role, and the interview questions seemed misaligned with what I had previously been told about the role.
It was an experience that was totally at odds with the first stage interview and made me wonder if I wanted to work there at all.
