Nine categories EM interviewers score you on — and how to prepare for all of them

Engineering manager interviews are scored across nine distinct categories, ranging from performance management and conflict resolution to technical judgment and vision, meaning strong preparation in only a few areas is rarely enough. Unlike individual contributor loops that test depth in a narrow technical domain, EM loops sample broadly, and gaps in even two categories can cost a candidate the offer. Most behavioural questions ultimately probe four things: whether the candidate ran a structured process, can name a specific tradeoff, owns outcomes without deflecting, and is clearly identifiable as the decision-maker within their own story. A practical preparation method involves writing down eight to twelve real situations from the past two years, mapping each to the nine categories, and identifying which cells remain empty — those gaps represent the questions most likely to catch a candidate off guard. Each story should then be rehearsed aloud, not memorised, targeting roughly ninety seconds and always ending with a candid reflection on what the candidate would do differently.
