There are 5 rounds of the interview process total. First round is basically competence testing for your verbal and numerical reasoning skills. Second is a case study and third is a personality test. These are really REALLY outdated. The personality test is literally a common quiz that is easily debunked as completely unempirical. You'd think that a company centred around organisational transformation and HR would have a better interview process than this. Plus, for an organisation that prides itself on its research, I felt like the process was lacking in its validity. The fourth and fifth stages are interviews with the director and the team respectively. That said, my interview experience was horrible. The interviewers gave increasingly hostile questions that were meant to see how much you would compromise on your own values (family time, work-life balance, even religious activities). The questions got more and more preposterous and pushy until I either couldn't answer them or refused to out of necessity.

I applied via linkedin. Was called up for the first round which was a test on excel. It was a very simple "test", what I would classify as rudimentary data visualisation. The HR was quite rude and "forgot" about me after the time was up. Received a follow up interview with management, the interviewer was 30 minutes late. During this time, I sat in the conference room with another candidate who was doing the first round. When they arrived I told them I was no longer interested in the position. Was told that I was wasting their time and should have not showed up. I do not understand this logic, since my decision was based on the fact that she did not respect me/my time.
