A recruiter contacted me via LinkedIn and the initial call went as expected: she described the role, asked me about my background, and answered questions I had about the company and the open rec. She also informed me of McKinsey's case interview style and how I could prepare for it since I have never had that type of interview before. Preparation methods included practice cases and helpful tips on McKinsey's website, a 60 minute non-evaluative case coaching session, a 30 minute evaluated coaching session, and 2 hour WebEx session. Beyond these, I also had one 60 minute call with the hiring manager, a 60 minute video interview with another researcher (30 minutes for a case and 30 for minutes for standard interview questions) within the team, and a 60 minute standard interview (also video) with an individual who was not in the team. The recruiter was great - knowledgable about the position and highly responsive in her communication. However, my experience with some of the other individuals was more negative. Of the six total calls I had, two were almost 10 minutes late to the call and did not acknowledge or apologize for it. I also had two interviews run long on time. I happen to be a very punctual person and do not have a high tolerance for lateness, particularly during an interview. Beyond this, it was also difficult to schedule interviews. I have a full time job and did not want to endanger that by skirting my responsibilities and skipping important meetings I had already set up. You would think that, since it was a recruiter who reached out to me, and not vice versa, they would be respectful of that. However, the interview scheduler made it very clear that their schedules were more important and were not flexible...even after they had to reschedule one of my interviews. Additionally, the scheduler accidentally mixed me up with another candidate and emailed me that I had another interview that had started 12 minutes ago, which nearly gave me a heart attack until I took a closer look at the name on the meeting invitation. During my 60 minute video interviews, I was interrupted a number of times because I wasn't providing the response that the interviewers were looking for. This is not why I rated it a negative experience - each company has its own technique - it's just a fact that I think others may find useful. At one point, the researcher within the team who was interviewing me essentially belittled the fact that all I did to overcome a challenge was "work really hard to meet the deadline". Again, this is not why I rated the process negatively. I think it would be helpful for potential candidates to know what type of personalities they should prepare for when interviewing with the company. If somewhat abrasive interviewers were the only issue, then I would simply consider it a challenging process. However, the fact that interviewers were aloof about the fact that they were late, in conjunction with the painstaking process of scheduling with an inflexible team, made this a negative interview experience for me.
