The contact I have had with the McKinsey recruitment team has been very pleasant. Unlike other management consulting firms, McKinsey flew me up to Johannesburg (from Cape Town) starting with my first in-person interview. They have also provided an interview coach who has been incredibly helpful in the preparation process. Communication is easy, admin for the trips is planned well in advance and accommodation in Johannesburg has been fantastic.

Rigorous but fair questions - mostly case based. Two sets of interviews x 2 rounds. You only get invited back for the afternoon if you pass the morning round. They expect a high degree of mental math and creativity. Worth prepping for standard case interview style questions, using frameworks but able to adapt them.
