4 separate interviews, each lasting between 45 to 75 minutes and with different subject matter experts. Interviewers seemed genuinely interested with what I had to say, asked great questions and showered praises of the company. It ended up being a massive waste of time and resources; the agency recruiter had told me that I was very keenly looked upon but it was all for naught as they've suddenly decided to hire internally at a more junior level instead. Regardless, I enjoyed the process up until the end.
