Difficult Interview

Application

I applied online. I interviewed at McKinsey & Company.

Interview

Long two-month process including a coding sample, 2 informational webinars, 2 practice "coaching" interviews, and 6 formal interviews. My recruiter was very clear about process and offered many tips. They clearly expect you to independently practice case interviewing.

    I applied online. I interviewed at McKinsey & Company.

    Interview

    Messy process.

    A recruiter was supposed to call me to answer my questions about the interview process after I had been selected. The next day, the recruiter said they will not call me, and instead they will put me straight into an introductory Zoom interview with a data scientist member. Ok!
    The data scientist interviewer was one of the most horrendous people I've ever seen. Never smiled, and never called me by my name, and was very arrogant and disrespectful.

    That aside, he revealed a severe lack of knowledge about the field. I found myself constantly correcting his naive mistakes. He also said he's been with the company for less than a year, and had little idea about the actual work. He ended the interview and I thanked him.

    The next day I received an email saying I was not selected for the next round! which I thought was a biased decision from a single inexperienced employee.

    I am quite surprised by this messy interview process that's supposedly conducted by one of the most respected companies in consulting.

    Interview Questions

    • No specific technical questions. The interviewer did not know the difference between a physical system and a computer model!   Answer Question

    Had online coding round that has questions based on R, python and stats. R and python was mostly based on specific packages that were used and would be difficult to answer if no experience with the packages.

    I only got an oa but it was very difficult and I didn't pass. Regarding the Python part, most of the questions were about data mining and machine learning. For R, the questions were all about importing data, cleaning data and data structures.
