The interview process was quick and efficient. The first stage interview with the hiring managers lasted around 45 minutes and the questions I was asked were quite general. I wasn't invited for a second interview; I felt their reasoning was slightly weak and communicated that to the HR contact I had been liaising with from the start. Sadly, unsurprisingly, I never got even an acknowledgment of my not-great experience, let alone a proper response, which is what I would expect from an experienced HR professional.
