I applied online. The process took 4 weeks. I interviewed at Strategy& (Singapore)
Interview
Fit interview: Skills needed to be a successful consultant
Case interview: Market entry into waste management sector; A novel case but largely manageable
Overall a really pleasant experience with 2 very good interviewers
3 interviews with 3 different people and one interview with HR before. Involved case studies of different difficulties. Everyone was very nice in the process and they answered all my questions
3 rounds of case interviews (principal, manager, and partner, respectively) , initial screening and HR interview (also might test for level of English). I also remember there being pymetrics after the initial screening
