There was an aptitude test, followed by 2 rounds of case study interviews and 1 round of HR interviews. All of them were eliminative. The whole process took about a week and the job offer came on the same day as the final interview.

I applied online. I interviewed at ZS Associates (London, England) in Jan 2026
Interview
Everyone was very nice and kind. Straightforward process. But took 2 months... was waiting for response for a week after each round.
HR, 3 case studies + fit interview
Also, was very hard to get interview invitation....
Easy if you are used to consulting interviews- was in one day, one behavioral round, two case interviews. They may try to stress test you a bit but overall was a pleasant experience. Definitely show that you are interested in healthcare in particular as that is their strong suit.
