At the start of the process, the company advised that there would be
1 x screening interview / call,
1 x video call interview,
1 x online assessment, and
1 x (in person) case study exercise and interview.
However, after going through all the above stages, the interviewers advised, during the in-person interview, that there would be one more interview with a C-suite executive. The reason provided was 'this role is important so the executive now wants to do an interview as well'.
