So, after applying there was what felt like many rounds of online tests - the usual type of thing, numerical reasoning, inductive reasoning and work style preferences. There is a short feedback report offered for each of these. The next step is the phone interview - 40 minutes or so of questions, nothing too strenuous. Competency based, so teamwork, leadership skills, dealing with setbacks, that sort of thing. There was a feedback report provided at this stage too. The next stage was the assessment centre. A resit of the online tests, presumably to confirm it was you who sat them. a written exercise with a time limit and a group exercise. Again, feedback was offered after this stage too. The final stage is the partner interview. mine was with two individuals, and was mostly competency based again. Very relaxed interview, chatty style. Feedback was offered after this stage also.
