    Application

    Case Interview Method

    Be well versed in basic geopolitics, maths, and be in engaging. Be willing to back up your numbers. Remember no one likes to feel stupid, most importantly an interviewer. I'd advise you to be prepared to be intimidated and tired, and even bored, and even asking WTF am I doing here? - things that consultants experience OTJ.

    Difficult Interview

    Application

    I applied through college or university. I interviewed at McKinsey & Company.

    Interview

    Online coding test from hackranker challenge test. The result will be posted in early Nov, which decided the possibility for rd 1. The interview for rd 1 will be in late Nov (but before Thanksgiving I guess).

    Interview Questions

    • Three coding problems, can choose whatever language I am comfortable with for each one. The first one is similar to sorting & searching question. I did it in R, but last four cases didn't pass because of the time complexity. The second and three are more like statistical modeling of predicting humidity (continuous response variable between 0 and 1) and predicting temperature (continuous non-negative response variable). My initial idea was to use autoregressive model but I had never learned it before. Screw on problem 2 but wrote something regarding what I thought as comment. The test duration was 120 minutes, and I submitted everything just before it ended.   Answer Question

    Difficult Interview

    Interview

    The online test (SHL) is really difficult. I was told by the person recruiting me that all the preparation I did for the case studies would more than prepare me well for the SHL but that was false; the SHL tests totally different capabilities and skills. And I'm pretty sure McKinsey automatically weeds out people who score less than 70-80% on the SHL and won't even offer them an interview.

    Junior Research Analyst Interview

    Anonymous Interview Candidate

    Negative Experience
    Average Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at McKinsey & Company.

    Interview

    After a phone interview with HR, a numerical reasoning test, and a verbal reasoning test, I went if for an interview. I had two interviewers, the first was a team member and the second was the hiring manager. The team member asked me basic behavioral questions along with questions about my background in research, nothing out of the ordinary. The hiring manager administered the case study. The case was nothing beyond what the company has told you to prepare for and is on the website, I did not find it particularly difficult. The interview process and content itself was not the reason for my negative review, though. Before my first interview started, I had the overwhelming feeling that the interviewer did not like me for whatever reason. It was apparent in his tone with me, his body language, and the questions he asked me. I felt incredibly uncomfortable. I have been through multiple consulting research interviews with other companies and have never felt this way before, regardless of the outcome of the interview. Further, the feedback I received from HR solidified this feeling, the feedback made from this interviewer made no sense, he said doubted my knowledge about a particular subject, but asked no questions about this knowledge during the interview. The feedback from the other interviewer was well received and I completely understood it. Besides the fact that this left me with a bad taste in my mouth, I was appreciative that HR did call me personally to tell me the outcome of my interviews. Not many companies do that these days, it was a nice personal touch.
