2 formal interviews, one of which was an initial call and the other was a task and competency based interview. The first interview wasn't conversational, it was more Q&A and didn't give much insight into what the role involved or what the company culture was like. I found out I was successful in progressing to the next stage by receiving a diary invite to a formal 2nd stage. The task in the 2nd stage interview was relevant for the job and I felt it tested the necessary skills. This was followed by competency questions which were tough but relevant - my only criticism of these is that when I received the feedback, it was evident that the interviewers were looking for very specific examples.
