I applied through the university career portal, and the process took 4 weeks.
The first round was on campus with a senior consultant, and it was pretty straightforward with mainly behavioural questions. We ended up speaking more about our travels rather than the job itself.
The final round was on site - 5 rounds with 5 consultants/managers. Questions were mainly behavioural. Each round was focused on one section of my resume. I would highly recommend knowing your resume thoroughly, and being yourself during the interview process. Everyone at the firm is really nice, and want to see if you fit the team.
