A free "top interview questions" list is usually the first thing candidates find, and it's not a bad starting point — it's fast, free, and gives you a general sense of what to expect. The honest comparison is about what happens after you have the list, not whether it's worth glancing at.
They're a reasonable primer on the broad shape of an interview — expect some behavioral questions, expect some role-specific technical questions, expect a "why this company" question. For someone who's never interviewed before, just seeing the categories laid out is genuinely useful.
A generic list can't know which tools, systems, or responsibilities the specific job description you're applying to actually names, so the technical questions are often a level too generic or entirely off-target. And even when a list includes sample answers, those answers aren't built from your resume — adapting a stranger's example answer to sound like your own real experience is the hard, time-consuming part that a static list doesn't solve.
KrackerAI starts from the same idea — here's what's likely to come up — but builds it from your actual resume and the specific job description you're applying to, not a generic template. Technical questions are pulled from what the job description literally names, and model answers reference your real projects and experience, so the output is closer to "already written for you" than "a template you still have to personalize."
If you're just starting to prepare and want the free primer, a generic list is a fine first stop. When you're preparing for a specific interview you actually care about, a report matched to that resume and that job description gets you further, faster.
