Interviewing at Koch
What the process looks like, and what Koch is really testing for.
Koch runs an interview process that blends HR screening with multiple interviewers, often in a panel format. Several roles report consecutive, sometimes back-to-back interviews in a virtual or onsite setting, including days that last multiple hours, and the atmosphere is frequently described as respectful and professional in the sample reports.
What the process actually tests shows up clearly in the topic mix: behavioral interviewing with STAR, communication skills, and Excel testing are prominent, alongside domain-specific technical areas that vary by role. The extracted topic list also includes integrity, hiring-manager technical evaluation, and for some roles deeper analytical areas like marketing analytics, time series analysis, marketing analytics, and accounting fundamentals.
Across the candidate reports you have, outcomes are consistently negative: the overall offer rate is 0.0%. Even with that, difficulty skews toward medium and hard, so you should expect structured questioning, follow-up on your reasoning, and role-relevant technical checks, plus a recurring emphasis on how you communicate and align with Koch values.
The topic data is unusually consistent about behavioral structure and communication, Behavioral Interviewing with STAR is at the top percentile, and Communication Skills is at percentile 88 to 100, so you should prepare answer narratives that are both STAR-structured and clearly explained, not just correct.
