I went through the standard 3 interview rounds for PhD potential hires.
Round 1 was the Interview Workshop & Initial Assessment (IWIA). For this stage of the process, I took an hour long standardized test and had two group "practice cases".
Round 2 was two one-on-one case+personal experience interviews.
Round 3 was three one-on-one case+personal experience interviews at what would become my home office.
After each stage of the process, I was given the chance to get feedback on my performance and talk with someone from the company. I started the interview process relatively uninterested in a job in consulting, but the people I met along the way completely changed my mind. I was extremely impressed by how friendly, helpful, and open everyone at McKinsey was throughout the interview process. The interviews were tough but fair, and I felt like I had a decent idea of what to expect at each round.
Interview questions [1]
Question 1
I spent time preparing to answer case questions, but I didn't spend as much time early on working on my answers for the personal experience part of the interview. After the second round, I realized the the PE portion needed plenty of prep to come out sounding coherent and polished. I'd highly suggest you come up with several stories about likely topics (leadership, passion, failure, conflict, etc.) and spend some time thinking through how you'd like to talk about them.
I applied in-person. I interviewed at McKinsey & Company
Interview
Website, online, teams meeting, in person meet up.
It was pretty straightforward and they knew what they were looking for. They had to do a couple of interviews to get a better understanding of my skills.

Interview
they let you prep for cases and do what the book says. this is only a question of how hard you prepared. then they take the people one by one and repeat again and again. sometimes the people who give you interviews have been there for less time than 1 yr
