As answered by people managing Codility and KrackerAI.
KrackerAI's answer:
General-purpose AI assistants (ChatGPT, Gemini, Claude) can help if you know how to prompt them well, but you're starting from a blank page each time and the answers aren't grounded in your actual resume. Other interview-prep tools often use fixed question banks that aren't matched to the specific job. KrackerAI combines both: real personalization (from your resume) and real specificity (from the job description), delivered as one ready-to-use report instead of a conversation you have to steer yourself.
KrackerAI's answer:
Instead of a generic question bank or an open-ended chat, KrackerAI builds one structured report from two real inputs — your resume and the actual job description you're applying to. Technical questions come from the tools and responsibilities the JD actually names, answers are grounded in what's really on your resume, and it includes a company research briefing — all in one document, not something you have to keep prompting for.
KrackerAI's answer:
Any job seeker, in any industry or role — from students and career changers to experienced software engineers, nurses, sales reps, and management consultants — preparing for a specific interview. It also serves corporate and recruiting teams who want to give multiple candidates structured, consistent interview prep.
KrackerAI's answer:
React and Vite on the frontend, Node.js/Express backend, Supabase (Postgres) for data and auth, Anthropic's Claude for report generation, Stripe for billing, Resend for email, and Cloudflare for hosting/edge routing.
KrackerAI's answer:
I built KrackerAI after getting frustrated with the overwhelming "night before an interview" routine—spending hours with 15 open browser tabs, Googling generic questions, and trying to manually map my resume to a long job description. I realized that 90% of effective preparation comes down to deeply connecting just two documents: your actual resume and the target job posting. Existing AI tools gave canned, robotic responses, so I created KrackerAI to turn those hours of chaotic cramming into a structured, presentation-ready study report in under five minutes.
