Most interview processes mix two fundamentally different kinds of questions, and treating them the same way in prep is a common reason candidates feel unprepared for one or the other. Knowing which is which — and what each one is actually testing — changes how you should study for them.
Technical questions test whether you can actually do the work: whether you know the tools, frameworks, and concepts the role requires, and whether you can apply them to a real problem. They're usually specific to the job description's named requirements — a data role gets SQL and modeling questions, a frontend role gets framework-specific questions, a support role gets product/tooling questions.
Behavioral questions test how you actually operate — how you handle conflict, ambiguity, pressure, failure, and collaboration. They're usually phrased as "tell me about a time when..." and there's rarely one correct answer; what's being evaluated is whether your story shows real judgment and self-awareness, not whether you hit a specific technical fact.
If the question has a right-or-wrong technical answer ("how would you design X" or "what's the difference between A and B"), it's technical. If the question starts with "tell me about a time" or asks how you'd handle a hypothetical people-or-process situation, it's behavioral. Some interviews blend both in the same question — a system-design question that also probes how you handled disagreement with a teammate on the approach, for instance.
KrackerAI's reports are structured around exactly this split — Level 1 Technical and Level 2 Behavioral are separate sections, each built from what your specific job description and resume actually support, so you're not guessing which kind of prep matters more for a given role.
